Installation problem Seafile with Docker

Hi all!
I have a server with pure Ubuntu 22.04
I follow all the steps according to the manual on the off site.
Docker works, but after installation Seafile the browser displays a “502 Bad Gateway” error at the address.

Seafile error in logs

seafile      | waiting for mysql server to be ready: %s (1045, "Access denied for user 'root'@'' (using password: YES)")
seafile-mysql | 2024-04-02 12:34:57 4688 [Warning] Access denied for user 'root'@'' (using password: YES)

Please explain what could be the problem?
