i ran the curl command as root user once more to upgrade the script!
and it was not asking me again for the user to run on ..

biggest problem was the ip yiimp binds to .. (external ip)
i dont want to use it for external connections - therefore i'm not setting any portforwarding from my router.

accessing the internal ip only gives me a blank page (on main pool address and on admin address).

i can't interrupt my gateway connection while installing cause it can't download then

i'm ready to reinstall my ubuntu 18 to start from scratch again if neccesary!
Just wanted to know if this should work or not

greetings - Astrali
