[solved] Admin login button unresponsive

My YunoHost server

Hardware: Raspberry Pi 4 at home
YunoHost version: recent (I can’t access the exact version)
I have access to my server : through the webadmin
Are you in a special context or did you perform some particular tweaking on your YunoHost instance ? : no

Description of my issue

The green login button to get to the admin interface is not active: hovering over it doesn’t change the cursor and clicking on it doesn’t do anything. I can’t log in as admin.

Same behaviour on Firefox or Chrome, both on linux.

That’s typically because the yunohost-api is down so you should debug it using SSH with sudo journalctl -u yunohost-api -n 50 --no-pager --no-hostname

Alternatively, there’s a known issue that the button is greyed out right after the postinstall but refreshing the page solves the issue

Thank you!
It turns out that it’s working now but I’m making a note of that for next time it happens.

I found a way to make it happen: just restart the Borg backup service (it stopped working some months ago, I’m trying to revive it).

sudo journalctl -u yunohost-api -n 50 --no-pager --no-hostname doesn’t tell me much, just this around that the time of restart:
