Nextcloud won't start due to missing favicon

[Mattias_Hedman]

I have Nextcloud installed using docker-compose. Due to issues uploading a huge folder (560Gb). I had to restart the docker compose set up, I saw that the Nextcloud container was recreated/updated.
After this Nextcloud refuses to start, web says “Internal server error”. Webtools says it cant load favicon. Well the container starts without issues. The ssl-certificate is loaded like it should.

  nextcloud:
    image: lscr.io/linuxserver/nextcloud:latest
    container_name: nextcloud
    environment:
      - PUID=1000
      - PGID=1000

        - "traefik.http.middlewares.nextcloud-dav.replacepathregex.replacement=/remote.php/dav/"
    networks:

    restart: unless-stopped

This is a first time for me with this error, what shall I do?

@Mattias_Hedman

After this Nextcloud refuses to start, web says “Internal server error”.

This is a generic error. Check your nextcloud.log as described in the support template.

I had to restart the docker compose set up, I saw that the Nextcloud container was recreated/updated.

I see you’re using the latest tag. You may want to use a more specific tag to avoid surprising major version bumps. See LSIO’s image docs.

Webtools says it cant load favicon

Failing favicon retrieval won’t prevent anything from functioning (to this degree). This is likely a red herring.

You are correct, this is a red herring.

This is what show now:

I know that the database is up and running. I have a healthcheck on it and I see it is up and running, the login works. And other services is using it.

Can you test DNS resolution for mariadb from within the Nextcloud container?

    networks:
        - frontend

Is the mariadb container on your frontend Docker network?

Without checking it that has to be it!
