Hallo zusammen,

kurz zur Einleitung:

Ich habe auf meiner Synology über den Container Manager u.a. folgendes laufen:
  • Postgres Datenbank
  • Synpase Server
  • Mautrix Signal Bridge
  • Mautrix WhatsApp Bridge
Informationen zum Setup (Bridges, Netzwerk) sind hier zu finden.

Dieses Setup lief anfangs auch gut zusammen. Allerdings macht seit einigen Tagen der Container der WhatsApp Bridge Probleme. In den Logs findet sich folgendes (Ausschnitt):

Ähnliche Meldungen gab es auch für die Signal-Bridge, allerdings waren folgende (13.10.24) die letzten Meldungen im Log hierzu und diese läuft wieder wie zuvor:

würde andeuten, dass der eigene Name (Containername mautrix-whatsapp-2) nicht gefunden wird?

Aktuell vermute ich, dass das kein Container Problem, sondern ein Docker Problem ist, sicher bin ich mir aber nicht (siehe z.B. https://github.com/mautrix/whatsapp/issues/291) , insbesondere da die Bridge am Anfang funktioniert hat. Der in den Logs angesprochene Link https://docs.mau.fi/faq/as-ping ist leider wenig hilfreich. Weitere Analysen im Container kann ich leider nicht vornehmen, da dieser kurz nach dem Start direkt beendet wird.

Leider bin ich aktuell etwas ratlos, wie ich mich dem Problem weiter nähern kann. Hat vielleicht jemand hilfreiche Erfahrungen oder Tipps?

Zur aktuellen Situation:

Ich habe das Setup auf einem separaten Docker-Netzwerk (bridge) aufgesetzt, und habe (bis jetzt) keine Probleme.

Von daher: Problem gelöst.
