Black Full Screen Issue When Accessing Mattermost Web App

Troubleshooting
1

Hi guys,

Black Full screen appears when I try to access the Mattermost web app. The login page loads fine, but after logging in, the BLCKscreen stays blank, and no interface elements are visible.

Iam using Mattermost version 7.10 on a Linux server with NGINX and PostgreSQL, and this started happening after I updated the Mattermost server and switched to a newer browser version. I have tried clearing the cache, restarting the server, and testing on different browsers, but the issue persists.

Has anyone faced this problem or knows how to fix it? Any help would be greatly appreciated. Thank you!

Hi @romromillys, thank you for reaching out! It sounds like this could be related to web app compatibility or configuration after the update. I’d recommend reviewing the Troubleshooting Mattermost issues guide for potential solutions. Additionally, ensuring that your NGINX configuration aligns with the Mattermost proxy setup might help resolve the issue. Let us know if you need further assistance!
