Fix: Slack desktop notifications and reminders not working

How to Fix Can’t Log In, “Slack Cannot Connect” or “Server Error” on Slack?

Suddenly finding that you can’t log in, encountering the “Slack Cannot Connect” or “Server Error” message on the Slack app at all of a sudden and looking for solutions to get back to the Slack app?

When it comes to working on projects as a team, communication is one of the most important things when it comes down to the nitty-gritty of everything. Effective platforms for communication are key in forming intuitive and informative discussions among team members, which is what Slack is able to readily provide.

For those who are familiar with Discord, Slack is an almost identical platform that instead prioritizes productivity and works in contrast to Discord’s agenda for gaming and social interaction. Slack offers its users access to channels to discuss things as well as bots that can automate certain actions or allow for a smoother work and productivity experience while using the platform.

The myriad of features that Slack has going for it makes it one of the best productivity platforms online and serves a more professional role for bigger companies than Discord has to offer. Despite the numerous advantages and features that Slack has to offer, several users have been finding themselves in a situation where they can’t easily log in to their Slack apps/accounts, making it impossible to access their workspaces.

 


Types of Slack Login and Connection Problems

Several users of Slack have been finding themselves unable to log in to their Slack accounts and workspaces. This problem is usually encountered in the login screen after signing out of the app or during the app’s startup if the previous login session hasn’t been signed out, which starts an automatic login.

Login problems with Slack usually come in the form of an error message that states that “Slack cannot connect”, as well as several things you can try out to fix the issue.

In other cases, some users have been receiving error messages that will indicate that something wrong happened with the servers, such as the “Server Error” message on Slack. Therefore, as the name suggests, this occurs due to server-side issues with the Slack service.

So, what Slack platform problem or login error are you encountering? Feel free to share your struggles in the comments below.  


 

In spite of the way you can encounter any log-in trouble with Slack, it is very unlikely you can access any of the content found within your workspace until you are able to successfully log back into your account without any issues.

To help ease the frustration of not being able to log in to your Slack account, we have curated this guide that aims to help you resolve any issues you have of not being able to log in to your Slack account. This guide here contains 3 reasons why you might be encountering problems with logging into your Slack account as well as 9 fixes that you can try out to have the problem fixed and even prevented in the near future.

Slack is mainly available on the desktop through a dedicated software app or through your Internet Browser. It is also available in phones for Android and iOS, albeit with fewer features than its desktop counterpart and certain limitations. This guide will cover all the available fixes for the platforms whenever possible and applicable.

Now with all the technicalities out of the way, let’s get started with getting you logged back into your Slack account and workspace.

 

 

Why Can’t You Log In or Cannot Connect to Slack?

1. A Server Problem in Slack

One of the most common reasons why you might have trouble with being able to connect to Slack and subsequently login into your Slack account might be something going wrong with the Slack servers.

For platforms such as Slack, having a server free from any issues is important when it comes down to using it without any issues along the way. Any known issues that are currently ongoing with the server are bound to cause problems, such as the inability to log in to your account, especially if the service is directly affected.

Consider checking the server status for Slack (Step 1), as you might only be having problems with logging as a result of an ongoing problem or maintenance. It will be in your best interest to track the status, as you can immediately re-login to your account as soon as the problem is fixed.

 

 

2. Connectivity Issues When Logging Into Slack

In relation to the previous reason, the next reason why you might have problems with logging into your Slack account can be the result of several connectivity problems getting in the way. It can be difficult to pinpoint the exact reason why you might be having problems, but fortunately, Slack has several things at its disposal that you can use to solve the issue.

One of the things that you can try out in Slack is by running a connection test provided by the official Slack team (Step 2), turning off any VPN connections you might have running (Step 3), resetting your internet connection (Step 4) to send a report to the Slack team together with any net logs you can provide (Step 6).

All of the solutions above are geared towards helping you with any possible connection issues you might have that might make logging into your Slack account difficult.

 

 

3. Performance Issues Related to The Slack App/Internet Browser

The last reason why you might be running into problems with your Slack app can be the direct result of performance issues with the app itself. It is not uncommon to find yourself encountering problems such as logging into your Slack account because of either the Slack app severely lagging or running into bugs and problems.

One of the two best solutions you can follow to quickly solve this issue is by clearing your Slack Cache and Data (Step 7) or by resetting your Slack app completely (Step 8).

 

 

9 Fixes For When You Can’t Log In, or Encounter “Slack Cannot Connect” or “Server Error” on Slack

1. Check For Slack’s Server Status

It should come as no surprise that an app like Slack relies on a server in order for it to function properly without any issues. Like many platforms for communication and message with other users of the same platform, it is important for Slack’s servers to be fully functional in order for you to have a smooth experience.

Check for the Slack’s server status to fix can't log In or connect to slack

 

Fortunately, Slack allows us a general look at its personal servers on this page as it will display to you the general health of the server as well as the individual status of each of its services. When it comes to logging into your Slack Account in particular, you want to keep an eye on the current service status of “Login/SSO”.

Check for the Slack’s server status to fix can't log In or connect to slack

 

Any other status besides “No Issues” that is found in the Login/SSO portion of the website will usually indicate a difficulty for users to properly log in to their Slack accounts if they haven’t already logged in previously. It is possible for users that had already logged into Slack before a problem popped up to use the platform without any issues unless the other features listed are also affected.

Besides that, you can also refer to third-party server status checkers, such as Downdetector, which compiles user reports and displays the current status of online services, like Slack. So, you can refer to the comments section and live map to see if users are reporting similar login, connection, or server errors, like the one you are encountering.

2. Run a Slack Connection Test

As we mentioned earlier, one of the reasons why you might not be able to log in to your Slack account might be a direct problem with your connection to the service. There can be several factors and reasons why you might be having problems logging into Slack despite having a good network connection.

Run a Slack connection test to fix can't log In or connect to slack

 

If the problem seems to be with your current connected network connection not connecting to Slack, then the team over there allows you to test your connection and how well it fares. You can head over to this page to check your connection to Slack, albeit only limited to the internet browser version of the service.

Regardless, getting connected through your internet browser and having no issues should indicate that you should be able to connect to another platform, with the inverse also being true if you aren’t able to connect.

 

 

3. Turn Off And Avoid Using a VPN When Logging In to Slack

For the most part, having a VPN turned on often brings us several benefits that make the service running worthwhile. Internet safety and even access to certain content that would otherwise be unavailable to use without the use of a VPN are one of the many reasons why you should consider having one in the background.

Despite these benefits, however, the use of VPNs can also be slightly problematic as you can have trouble with using services such as Slack and the like. Slack is a workspace platform that allows you the benefit of getting connected with other team members, which a VPN can impede with its own features.

This would often lead to your account getting falsely flagged for an offence and even lock you out from logging into your account for security reasons. With this in mind, we recommend turning off your VPN connection while trying to log in to Slack, then restarting Slack and attempting to log in to your account after turning it off.

For application-based VPN services, you easily disconnect or disable your VPN connection within the application settings.

Additionally, usually, using low-quality VPN services can cause miscellaneous platform and connection problems like this, as it funnels numerous users through a single IP address that Slack has already identified as fraudulent. Therefore, if you want to access websites and applications such as Slack and garner all the other security benefits that VPNs bring, we highly recommend subscribing to a premium VPN subscription. In this day and age, there’s a tonne available at affordable rates!

If you ask us, we recommend NordVPN, which is fast for as a daily driver, keeping us protected at all times even for when we’re using our daily apps, including Slack. So, do check out NordVPN and their insanely-valued deals for a good-quality VPN subscription!

4. Reset Your Internet Connection

One of the reasons why you might have a hard time logging into Slack might be with the current network connection you have saved into your device. It is possible for the same internet connection to suddenly not work properly because of something going wrong with the connection settings.

Resetting your internet connection is one of the fastest ways to solve this issue, as it allows you to form a new connection instance and avoid the problems you had in the previous ones. Here’s how you can do it:

 

For Desktop (App & Internet Browser)

  1. Open your Command Prompt as an admin by typing “CMD” in your Search bar, and right-clicking then selecting “Run as Administrator”.
  2. In the Command Prompt window, type in “ipconfig /release”, hit enter, and wait for it to finish.

5. Reset Your Device’s Network Settings

Resetting network settings can be a quick and effective solution to fix the “Slack Cannot Connect” or “Server Error” issue that many users face when trying to log in to Slack. This fix essentially clears out any saved network settings, such as Wi-Fi networks or VPN configurations, that may be causing conflicts with Slack’s connection.

When network settings are misconfigured or outdated, it can lead to issues with Slack’s server communication, resulting in login problems or error messages. By resetting network settings, the device establishes new connections and eliminates any potential conflicts that may be causing the issue.

In addition, resetting network settings can also help to resolve issues related to slow internet connectivity or weak signals, which can often cause Slack to fail to connect. By doing so, users can restore their device’s network settings to its default state and ensure a stable connection to Slack.

7. Clear Your Slack Cache And Data

More often than not, one of the main reasons why you might have a problem with Slacks and other apps might have something to do with the internal files, like the data and cache getting corrupted.

Rather than going through the entire process of reinstalling a Slack app altogether, cleaning out your cache and data makes a great alternative to fix the problem.

Here’s how you can quickly clean out your Slack cache and data through these steps:
