Jenkins UI Turns Black After Login – How to Fix?

Using Jenkins
1

Hi Everyone,

After updating Jenkins, I noticed that the web UI goes completely black screen after logging in. The login page works fine, but once authenticated, the dashboard does not load, and I can’t access any jobs or settings.

I have tried:

Restarting Jenkins and checking jenkins.log for errors.
Clearing browser cache and testing in Chrome, Firefox, and Edge.
Running Jenkins in safe mode (/safeMode) to disable plugins.
Checking proxy settings I am using Nginx/Apache.

Has anyone else faced this issue? Could it be caused by a plugin conflict, Java version mismatch, or rendering issue? Any suggestions would be appreciated!

Have you tried accessing it directly without the reverse proxy to check whether the issue is with the proxy?
Additionally, you might want to try restarting Jenkins using the restart page:

http://[yourjenkinsaddress]/restart

You could also consider disabling any plugins that you suspect might be causing the problem.
