Hi @lamdangm, can you help try these troubleshooting steps first:

  1. Try to clear cache and reload the app from View > Clear Cache and Reload or by pressing CTRL/CMD+SHIFT+R.
  2. Quit the app and restart it to see if the issue clears.
  3. Disable GPU hardware acceleration from File > Settings on Windows, by deselecting Use GPU hardware acceleration .
  4. If you are using a special video driver such as Optimus, try disabling it to see if the problem is resolved.

Thanks Amy, I did clear cache and disabled GPU acceleration in setting page and still run into this same problems

@lamdangm is this a local dev environment you’re running the problem into or a hosted server somewhere?

This is a hosted server deployed by my company. I just ran into this problem today.

Are other members of your team seeing the same issue? Might be worth speaking to the team maintaining company’s Mattermost instance as it’s possible they upgraded recently and may have caused this issue.

They seem using it fine lately. I can still access the site on my android app, but somehow cant use it on my desktop or even Web browser. Thanks for the suggestions.

Do you mind trying Chrome’s incognito mode?

yeah i did try that, even Guest window and Edge but it still stuck and showing blank site after entering my credentials info.

@lamdangm, what server version are you on?
