For some reasons, the seafile-mysql container immediately spams this warning, and during this time, Seafile is not accessible. I tried restarting, updating the compose but got the same error.

The seafile doesn't have any suspicious logs:

The Aborted connection ... (Got an error reading communication packets) warnings in the MariaDB logs are a known cosmetic issue in Seafile's Docker deployment. They occur because certain Seafile components or background tasks do not always close their database connections gracefully. While they spam the logs, they generally do not impact the functionality of the server.

However, since you mentioned Seafile is inaccessible, the focus should be on the Nginx and Seahub configuration. Your Nginx logs show:
nginx: [warn] conflicting server name "" on 0.0.0.0:80, ignored

This typically indicates that the SEAFILE_SERVER_HOSTNAME variable is either missing or incorrectly set in your docker-compose.yml or .env file, causing Nginx to default to an empty server name.

To help diagnose this further, please provide the following:

1. Your docker-compose.yml (redacting sensitive information like passwords).
2. The contents of seahub.log and seafile.log from the seafile-data/seafile/logs directory.
3. The Nginx error logs from the container (usually located at /shared/logs/nginx/error.log).

Also, ensure that your SEAFILE_SERVER_HOSTNAME matches the domain or IP you are using to access the server and that the protocol (http/https) is correctly defined.
