Seit letztem Wochenende benimmt sich "Grommunio Web" bei meinem Mail-Server komisch. Ich kann mich zwar anmelden, aber danach bleibt die Seite "stehen". Laut den Entwickler-Tools im Browser will die Seite auf die URL "https://grommunio.accelsukiru.de/web/grommunio.php?subsystem=webapp_1660570728716" zugreifen (was auch richtig ist) und bekommt immer als Rückmeldung den Fehler "502 Bad Gateway". Aus dem NGINX-Log "nginx-web-error.log" konnte ich folgenden Fehler entnehmen.

Das Problem tritt unabhängig vom Browser auf. Eine Bereinigung der Caches hilft leider nicht.
Hat jemand eine Idee, was der Fehler ist und wie man diesen beheben kann?
Zu dem Zeitpunkt,als es aufgetreten ist, habe ich keine Updates installiert oder dergleichen. Ich habe heute Mittag, weil cih dachte, dass es vielleicht helfen könnte, per zypper die neusten Updates installiert und den Server einmal neugestartet ... leider ohne Erfolg. Die Mail-Dienste (POP, IMAP, SMTP und MAPI) funktionieren weiterhin und auf das Admin-Interface kann ich auch noch ohne Probleme zugreifen..
