Cannot login after some time of the server working.

It is not possible to login after some time of working.
The combination of username and password is accepted but nothing happened on the logging in webpage.

New user singing up gives the same result. Restarting server with the same label_studio.sqlite3 file does not help.
Tried Chrome and Safari.

The user can be observed with
label-studio user --username ...

Label Studio version 1.7.3
Docker image heartexlabs/label-studio:hf-1.7.3

Steps to reproduce:
Run the server, create user, wait for a couple of days.

I observed that same behaviour for 1.8.0 and without docker.
