Describe the bug
About 20% of the time update manger 7.1.4 Mint 22.3 displays a red banner telling the user to switch to a mirror.
Screenshots

To Reproduce
Cannot be reproduced on demand. It just happens
Expected behavior
Don't want the warning unless it's needed.
Distribution:
Linux Mint 22.3
Software version:
7.1.4
Additional context
If I ignore the warning and let it open the sources and immediately cancel without any changes and then doing a refresh, mintupdate just keeps on going as usual.
If I ignore the warning, I can still install update and do a refresh.
A refresh works but does not remove the banner.
