Does running sudo yunohost tools regen-conf apt fixes the issue ?

It was my modem, restarting it solved the problem.

Today I had similar issues, the change I had in mind was adding the list “no google” on adguard home, I disabled it and it came back again working as before, could it be some DNS blocking of ADG?
