I am able to log into the web interface of Pi-Hole on my PC but am unable to login to Pi-Hole admin to change the passwords via a terminal session on the Ubuntu host of pi-Hole
I have a Virtual Ubuntu machine on VMare esxi and Pi-Hole was installed inside of Ubuntu yesterday
I have changed nothing on Pi-Hole as my admin credentials do not work and I cannot access via ssh
Ubuntu. Pi-hole is not involved in sshand your local username/password. Once you're logged in via ssh you can change the password for Pi-hole's web GUI via pihole -a -p
to resolve your issue with logging into Pi-Hole admin via a terminal session on your Ubuntu host, you can try verifying your login credentials, checking network connectivity, verifying Pi-Hole installation, and resetting your Pi-Hole admin password.
