Ich habe ein kleines aber kritisches Problem, was in zwei Tagen den BigBlueButton Server lahm legt.
Ich habe BBB mit dem offiziellen Installer Skript installiert und ein Zertifikat über LetsEncrypt bezogen. Siehe hier: BBB und LetsEncrypt. Das Ganze läuft auch schon seit 88 Tagen wunderbar. Jetzt wird aber das Zertifikat ablaufen denn der cronjob mit
/usr/bin/certbot renew
versagt mit der Fehlermeldung:
