Hallo,
wir haben ein Discourse-Forum für Scala-PL-Nutzer, das jahrelang einwandfrei funktioniert hat:
Letzte Woche habe ich auf die neueste Version aktualisiert, indem ich „./launcher rebuild app“ ausgeführt habe. Seitdem erhalten wir sehr häufig den Fehler „Oops - Error 500“. Dieser tritt auf, wenn die Website bereits besucht wurde. In einem privaten Browserfenster funktioniert alles einwandfrei. Das Löschen der Website-Daten im Browser behebt das Problem also für eine Weile, aber es tritt erneut auf.Started GET "/" for 127.0.0.1 at 2026-09-03 09:57:56 +0000 Processing by ListController#latest as HTML Rendered layout layouts/application.html.erb (Duration: 391.6ms | GC: 229.5ms)Completed 500 Internal Server Error in 474ms (Views: 392.5ms | ActiveRecord: 0.0ms (0 queries, 0 cached) | GC: 236.0ms)
Hast du eine Idee, was falsch ist und was ich tun könnte, um das Problem zu lösen?
Fabien
Bei genauerer Betrachtung lässt sich die „Fehler 500“-Meldung durch das Löschen des _t-Cookies beseitigen, doch der Fehler tritt nach der erneuten Anmeldung – möglicherweise nach etwa einer Stunde – wieder auf.

v2026.9.0 wurde noch nicht veröffentlicht – meinst du die Entwicklungs-/Latest-Version?
Ich habe keine bestimmte Version festgelegt, daher vermute ich, dass standardmäßig die neueste Version verwendet wird (gemäß "tests-passed" is now "latest" ).

Kannst du in /logs den 500-Fehler finden und den Fehler samt Backtrace teilen?
Ich habe das nur in den Logs (production.log), nirgendwo sonst:Started GET "/" for 127.0.0.1 at 2026-09-07 08:05:50 +0000 Processing by ListController#latest as HTML Rendered layout layouts/application.html.erb (Duration: 164.0ms | GC: 13.5ms)Completed 500 Internal Server Error in 248ms (Views: 164.7ms | ActiveRecord: 0.0ms (0 queries, 0 cached) | GC: 15.9ms)
Ich habe keinen Weg gefunden, mehr Debug-Informationen zu erhalten.
Übrigens habe ich auch /safe-mode ausprobiert, aber das ändert nichts…

Es ist unter dem Pfad /logs zu finden, sofern dieser nicht ebenfalls fehlschlägt.
Entschuldigung, ich habe mir die Container-Logs angesehen.

Betreibst du eine Art Proxy – kannst du die Architektur beschreiben?
Es sieht so aus, als würdest du den String “unix:” in das Feld ip_address übergeben …
Dies könnte eine Fehlkonfiguration oberhalb von Discourse sein.
Es wurde ein ähnliches Problem gemeldet und hier gelöst, das mit Caddy zusammenhing:
@Falco @satonotdead
Ich habe es geschafft, es zu beheben. Ich habe eine gute Weile gewartet, um sicherzugehen, dass es wirklich behoben ist, und es scheint, dass es der Fall ist.
Vielen Dank für die Hilfe!
Ich habe genau diese Konfiguration:
In diesem Beitrag zeige ich Ihnen genau, wie Sie Discourse hinter einem Nginx Reverse Proxy ausführen. Und das unter Verwendung der unterstützten Installationsmethoden.
Voraussetzungen:
Gültiger Domainname.
Gültiges SSL-Zertifikat.
Gültige DNS-Einträge, die auf den Domainnamen zeigen.
Gültiger, funktionierender E-Mail-Server oder SMTP-Anbieter.
Funktionierender Nginx Reverse Proxy und die Möglichkeit, auf die Instanz zuzugreifen und das SSL-Zertifikat für die spätere Verwendung zu erstellen.
V…
… nur fehlte darin die Zeile “proxy_set_header X-Real-IP $remote_addr;”.
Daher könnte es damit zusammenhängen.

Ja. Ich hatte dasselbe Problem und habe einfach diese neue Direktive proxy_set_header X-Real-IP $remote_addr; in der Datei /etc/nginx/sites-enabled/myforum-ssl.com hinzugefügt, und das scheint zu funktionieren.
Danke @Fabien_1015 @merefield
