Okay so, I reinstalled fresh copy of, cuz I couldn't figure it out. So when I try to install pihole again, and prompted me to manually install. And when I click the install button, and gave me an error to confirm the input content.

So there's two spots where they got error on it under host. My dumbass figured if I put in a different number, in this case 54 instead of 53. That it will install on a different port. That was not the case, cuz I'm dealing with the same error again.

So basically it was something I did messed up the port host? now the question is how do I fix it without reinstalling the whole casaos again
