At first our problem started off with Let’s encrypt. We were supposed to renew our certificates for the websites and we simply couldnt. We thought it was because we couldnt use the Let’s encrypt add on because it was saying that there was already other stuff using ports 80 and 443, so we were trying multiple stuff there and didnt succeed. A friend of ours who tried helping us deleted fullchain.pem and privkey.pem. We then deleted Let’s encrypt and downloaded it again in hopes of restoring the deleted files and accessing the add on but we ran into a couple problems there where i eventually tried restarting home assistant and now i cant access the website at all.
What are you running HA on ?
