Auto login failed (No user found)

[Findorgri]

I'm trying to deploy dotCMS 5.3.9 docker image (dotcms/dotcms:5.3.9) in an Ubuntu VM. I'm getting an error when running docker-compose up using the yaml file provided for the 5.3.8.4lts image here: https://github.com/dotCMS/docker/blob/v5.3.8/examples/02-single-node-demo/docker-compose.yml
The error is about the login, which apparently the application fails to do by its own, and I can confirm that I am unable to do so manually through the browser as well.
A preview form the logs I attached:
[10/05/21 08:59:55:568 GMT] INFO util.SecurityLogger: class com.dotmarketing.cms.login.factories.LoginFactory : Auto login failed (No user found) from IP: 172.21.0.1 : com.dotmarketing.exception.DotRuntimeException: Could not execute query -- ip:172.21.0.1,user:null [10/05/21 09:00:10:606 GMT] WARN util.JDBCExceptionReporter: SQL Error: 0, SQLState: 42P01 [10/05/21 09:00:10:606 GMT] ERROR util.JDBCExceptionReporter: ERROR: relation "user_proxy" does not exist Position: 1564
The only change I have made in the yaml file is to change the version of dotcms docker image from latest to 5.3.9.
Thing I have tried:

1. To deploy the dotcms/dotcms:5.3.8.4lts image. Resulted in the same error.
2. To deploy the latest image and it works fine, but I need specifically the 5.3.9 version.

I'm attaching the logs where the problem can be seen more clearly.
