Don't succeed to connection


What is the problem?
I don't succeed to connect with my account on Octoprint on port 5001. On port 5000 it works. I think my account on port 5001 is incorrect.
I have this message:
Login failed
User unknown or wrong password
What did you already try to solve it?
I tried on port 5000 it is work, so I think it is a problem with parameters of account on port 5001.
