Can't delete expired certificate

[mrmarkuz (Markus Neuberger)]

Regarding the timeout please also check if the needed port is opened and loki is running:

X509 certificate verification - cert4android

This sounds odd: I see two possible reasons for the timeout. Let’s Encrypt servers cannot reach your NS8 node on port 443, or 80 (if you installed Traefik before version 3, released during milestone 8.4) Loki is down. Check if the System Logs page is working correctly.
