Can't login with android app

Server version : 10.6.4 (window)
App version 2.0.1
I cant login with app
If I connect with chrome, it works.
and If I connect with another android phone, it works.
Only Galaxy A51 does not log in.
I can connect to the server, but if I try to log in, it says Connection Failure
How can I solve it?

Recently, I did update my mobile phone software.
It used to work well, so I think it might have been in conflict with the mobile phone software.

This issue can happen when the name of your device uses special characters. We’ve fixed that bug in our next release but as a workaround you can change your device name in your device settings.
