Unable to access Seafile

Seafile Server
,
1

I set up Seafile behind a Traefik reverse proxy, but I can not access it. When I try to access the domain I get error 521 from Cloudflare.
This is my docker-compose.yml:

services:
  db:
    image: mariadb:latest
    container_name: db
    hostname: db
    environment:
      - MYSQL_ROOT_PASSWORD=$MYSQL_ROOT_PASSWORD  # Requested, set the root's password of MySQL service.
      - MYSQL_LOG_CONSOLE=true
    volumes:
      - seafile-db:/var/lib/mysql  # Requested, specifies the path to MySQL data persistent store.
    networks:
      - seafile

  memcached:
    image: memcached:1.5.6
    container_name: seafile-memcached
    entrypoint: memcached -m 256
    networks:
      - seafile
          
  seafile:
    image: seafileltd/seafile-mc:latest
    container_name: seafile
    hostname: seafile
    volumes:
      - seafile-data:/shared
    environment:
      - DB_HOST=db
      - DB_ROOT_PASSWD=$MYSQL_ROOT_PASSWORD  # Requested, the value should be root's password of MySQL service.
      - TIME_ZONE=Europe/Berlin  # Optional, default is UTC. Should be uncomment and set to your local time zone.
      - SEAFILE_ADMIN_EMAIL=$SEAFILE_ROOT_USERNAME # Specifies Seafile admin user, default is 'me@example.com'.
      - SEAFILE_ADMIN_PASSWORD=$SEAFILE_ROOT_PASSWORD     # Specifies Seafile admin password, default is 'asecret'.
      - SEAFILE_SERVER_LETSENCRYPT=false   # Whether to use https or not.

In my Traefik UI I can see that Traefik recognizes those labels and creates the relevant router.

What am I doing wrong? I also tried activating the Cloudflare developer mode thinking this was a caching bug, but that did not help either.

Have a look at the logs. Think /opt/seafile/logs

I’m not quite sure which log you are talking about, so I had a look at a few of them:

  1. All the access logs in /nginx are empty, so my requests never reached Seafile?
  2. There were no errors in dpkg.log and alternatives.log, so there were no errors during startup?

As I said, I’m not quite sure how to interpret these and I’m not even sure that I looked at the right logs. Since I used Docker with volumes, I guess the logs you were talking about /var/lib/docker/volumes/seafile_seafile-data/_data/logs/var-log, right?

Could be. I’m not using the docker version.
