Account issue invalid detials

don’t know what happened but all of a sudden I can’t access my hestia control panel. keeps showing

|Invalid username or password.|

but I know I didn’t change anything. i saw a command online to change the password still the same thing. please is there a way to create another system user. or how can I access the panel

Check /var/log/hestia/auth.log and see what is wrong

Am I doing this within my SSH panel

Yes.

Login vía ssh and then run

cat /var/log/hestia/auth.log
