White screen after login to Cockpit

devfx11 · September 29, 2022, 9:31am

Hello

I updated all my packages and logged into cockpit and it was still work
Then i was working in the “Terminal” part of cockpit and then somehow it stopped suddenly.
After a restart i can login to cockpit but all i get is a white page
Refreshing the page gets me back to the login screen
The old manager works just fine.

I looked at the /var/log/messages and i see some sessions getting created then i see session timed out.
Could it be that somehow the “Terminal” session got stuck somewhere and the issue is somewhere there ?

How could i debug this and how could i fix this ?

The old server manager works fine but i think there are options that are only available on the new server manager / Cockpit interface.

If anyone could help me out with this i would greatly appreciate it.

Have you tried clearing cookies and browser cache?

Yes i have tried in different browser as well and on different pc and still the same

I did the update, there were around 80 packages.
After that i rebooted the machine and only later it stopped working.

I was in “Terminal” when it suddenly stopped working and i rebooted it and issues started after that.
I will link /var/log/messages when logging in.

Check the web browser console for warnings/errors.

I removed the new manager since and was using the old one
Have to reinstall it again and test.

I removed the new manager and now re-added it via the old manager interface
The old manager when going to the software packages said i need to press the clean yum button, so i did.
After that i added back the new server manager.
And now it works
I still going to paste the /var/log/messages here when logging in. There seems to be 30 root sessions ? Why ? I didnt even login. There are also some other interresting messages there.
