Invalid request No data was saved

[EnergeticMrMask]

Hello.
I am trying to implement an email service using docker-mailserver and roundcubemail through Docker in one server.
Everything was going smoothly until I tried to log into the email using roundcubemail.
I entered the correct username and password, but it prompted me with Invalid request! No data was saved.
I didn't find any relevant solutions about this online. I found a related discussion in Roundcube's issues, but I think the solution provided doesn't seem suitable for Docker.
The docker-mailserver seems to be running fine; the problem should be with Roundcube Mail. I believe there is an issue with my configuration, but I don't know where the problem lies.
This is my docker run command, which I modified based on the docker run instructions and compose file from the examples and the README.

docker run \
  --name roundcubemail \
  --network host \  #I also tried use "-p 80:80" here, but there is no different
  -v /etc/docker/roundcubemail/config/data:/var/www/html \
  -v /etc/docker/roundcubemail/config/db/sqlite:/var/roundcube/db \
  -e ROUNDCUBEMAIL_DEFAULT_HOST=localhost \ #I also tried use "192.168.x.x" which is the server's IP and "mail.mydomain.com" which point to IP 192.168.x.x. but there is no different
  -e ROUNDCUBEMAIL_SMTP_SERVER=localhost \
  -e ROUNDCUBEMAIL_DB_TYPE=sqlite \
  roundcube/roundcubemail

and the run log is as follows
