The credentials you entered are not valid

[Kaj-cyber]

Dear whom it may concerns,

I'm using Unbuntu20.04 on my server.

After I'm at local host http://localhost:9000/, I cannot login using the e-mail and password [email protected] vdjviz1

The error 'The credentials you entered are not valid' was raised.

Would you please help me get through this?

Best regards, Kaj
