My server is a 4.4-x fully updated until last week. When I attempt to run the update module from the web interface, the screen gets stuck at “…loading data…” and the cursor sits there and spins. After several minutes, I get an “An unknown error with status code 502 occurred while connecting to the server, please try again later.” pop up on the screen.
When I log into the server via the ssh console, and run “univention-app update” the process is extremely slow, taking literally minutes between each line when downloading from https://appcenter.software-univention.de
I tried changing the external DNS of the server from 1.1.1.1 and 1.0.0.1 to 8.8.8.8 and 8.8.4.4
I tried restarting the server.
I tried shutting down the vmWare host and restarting the UNC server.
No improvements at all.
I suspect some sort of timeout or delay accessing the univention servers. But, I don’t know what else to check. Firewall?
The kopano, webapp, and nextcloud services seem to be running just fine and can be accessed as intended.
Suggestions?
