Username or password is incorrect :(

Greetings to all, excuse my translation of google, I have a big problem, I hope you can help me:
I installed gitea on a debian 9 server which has worked excellently, until the day when trying to log in with the administrator account, it says “Username or password is incorrect.”. Try changing the password with the command “gitea admin change-password --username myname --password asecurepassword”, and checking the DB I realized that if I change the password but still can not enter. any advice?

best of luck https://haveibeenpwned.com https://github.com/DivineOmega/password_exposed
