I got the Nginx Proxy Manager set up but when I go to the web interface of the Nginx Proxy Manager i get asked aobut an email and password, and nowhere did I find any manual that tells me how to create an account or where to put those credentials…
I think if you go to the add-ons GitHub there is an open (or possibly closed) issue on this. It tells you how to solve it. It comes of NPM starting up when MariaDB was down or something.
