How to Fix Slack Not Working on Browser

Wondering why Slack is not working on your browser?

Slack is one of the best communication tools for businesses and teams to collaborate. The platform is available for all major operating systems, including Windows, macOS, Android, and iOS. 

There’s also a dedicated website for users who don’t want to download the app. 

Unfortunately, Slack’s website is not always available, and it can be down for various reasons. The servers could be undergoing maintenance, an unexpected error occurred on Slack’s end, or there’s an issue with your browser. 

Whichever the case is, this problem can affect your productivity and should be addressed right away. 

Today, we will show you what to do if Slack is not working on your browser. 

Let’s get right into it!

1. Check Slack Servers. 

Before making changes on your device, the first thing you should check if Slack is not working on your browser is the status of its servers. This way, you can identify if the problem is coming from your end or Slack’s side. 

You can do this by visiting Slack’s System Status page, where you can check the status of their services. 

Slack Service Status

If Slack’s servers are currently down, the only thing you can do is wait for their team to fix the problem. However, if there’s nothing wrong with the servers, the issue could be on your end. 

Proceed to the following method below to address the issue on your device. 

2. Restart Your Browser. 

The first thing you can do if Slack is not working on your browser is restart it. This way, you can ensure that your browser’s application files are loaded correctly and fix any temporary errors that may have occurred. 

Simply close your browser for several seconds before relaunching it. Once done, go back to Slack to see if you can access their website. 

Go to the next method below if Slack is still not working on your browser. 

3. Restart Your Device. 

If restarting your browser does not work, you can try restarting your device. There could be a problem with your device’s system, which causes your browser not to function correctly. 

For Windows, here’s how you can restart your system: 

  1. On your computer, click on the Windows icon in the Taskbar to open the Start Menu
  2. After that, go to the Power Options tab.
  3. Finally, choose the Restart option to reboot your system.

  2. Next, choose the Restart option.

After restarting your computer, go back to your browser and see if you can access Slack’s website. 

4. Check Your Network Connection. 

A slow internet connection could also be the reason why Slack is not working on your browser. Since Slack is an online service, you’ll need a stable connection to access it without encountering issues. 

To check if your network is the problem, run a speed test using to measure your network’s current bandwidth.

If the test shows that your network is the culprit, restart your modem or router to re-establish the connection with your service provider’s servers. Unplug your router from the outlet and wait for 5 to 10 seconds before plugging it back in.

Once done, perform another test to confirm if the problem is solved. If not, contact your ISP and ask them to fix their service. 

5. Turn Off VPN. 

If you’re using VPNs, it may be causing the issue with Slack. VPNs or virtual private networks protect your data by filtering your activity through their servers and changing your IP address to keep your identity private. 

However, this process can cause delays and interruptions to your network. When this happens, your browser may struggle to communicate with Slack’s servers, explaining why the website is not working. 

To avoid this, disable your VPN first before accessing Slack on your browser.

On the other hand, you can try other VPN providers such as PureVPN if you’re not comfortable going online without protection. Compared to other VPNs, it doesn’t interfere with your network’s flow and keeps your connection stable while protecting your data. 

6. Clear Your Browser Cache and Cookies. 

Browsers use temporary data generated from your activity to improve their performance. These data are called caches and cookies. Unfortunately, they can accumulate over time and cause issues to your browser instead of boosting its performance. 

To fix this, check out the steps below to clear your browsing data: 

  1. First, open your preferred browser and access its Settings
  2. After that, navigate to Privacy and Security
  3. Now, click on Clear Browsing Data and change the Time Range to All Time
  4. Lastly, include caches and cookies in the process, then hit the Clear Data button to start.

After clearing your browsing data, go back to Slack and see if you can access the website. 

7. Disable Browser Extensions. 

Some websites are not compatible with browser extensions. Although there’s no list of extensions that don’t work with Slack, you can try disabling your extensions if Slack won’t load on your browser.

Here’s how you can disable your browser extensions: 

  1. On your computer, fire up your browser and access the Settings
  2. Next, click on the Extensions tab from the sidebar. 
  3. Finally, disable all your extensions and restart your browser.
