I have an incredibly silly/stupid problem.
Brand-new blank installation of Debian 11 > installed docker > installed portainer via docker-compose > used the recommended AIO compose script for the stack > > > everything is working fine, except…
I fubared a DNS entry testing port 443. In correcting the error I wrongfully (accidentally?) entered a FQDN into the box on the set up page and it the button.
It’s a problem, because what I really wanted to do was restore from backup.
Now when I return to https://[my-domain]:8080 I immediately go to the “containers” page in the system will not let me return to the “setup” page. I get an error on the page that says “already installed”.
I shut down the containers, remove the containers, tried to find the persistent files to no avail.
Short of uninstalling docker and reinstalling… How do I reset the installation?
Many thanks in advance.
