Hallo Community,
ich bin gerade am verzweifeln… Mein Nextcloud Image NCP läuft auf einem rPI 3. Ich habe diesen zuletzt vor 1 Woche aufgesetzt. Bis heute klappte alles
Zugriff über Wlan
Zugriff extern usw.
Heute morgen musste ich meinen Router rebooten lassen, da er keine DSL Verbindung hinbekommen hat. Nach 2 Minuten reboot ging alles wieder … dachte ich… Leider geht meine Nextcloud nun nicht mehr online, also kein Zugriff von extern. ZUgriff über Wlan klappt.
Ich habe gesehen, dass mein Router den Dynamischen DNS deaktiviert hatte sonst habe ich alles geprüft und finde beim besten Willen keinen Fehler, da ich ja auch nichts verändert habe 
Ich sehe in NCP das es keinen Intenetcheck gibt. letsencrypt meldet auch fehler, daher gehe ich davon aus es liegt daran…
hat jemand eine Idee für mich?
und noch die Meldungen von letsencrypt
