V-change-user-password dont work

I can’t access the Panel: I enter Admin and Password but they don’t work. I logged in as root with SSH and gave the command: v-change-user-password admin newpassword and then rebooted but the same problem occurs.
If I try to install HestiaCP again on the existing one, do I lose my data?
Is there a different way to regain access?

Check log files

I login as user but not as admin and cannot change password to admin

Try a password composed only of numbers and letters.

Done but it doesn’t work. Thanks anyway for your reply. I install from scratch and copy the data
