Pi-Hole password and help plz!

I want to know if anyone knows the Pi-Hole password or why I can’t change it? I have tried the one on the page for installing and the one it gives you when you start the app I have even tried to reset it in the terminal (pihole setpassword), and this every time

I do not know what the default is for the app, but the old login used to be pi password raspberry.

Have you tried opening pihole from the Umbrel UI? it gives you the default password
