Hi all, Is it possible to self host cal.com on something other than localhost? When I try to change the NEXT_* URLS I still end up with issues. After running "Yarn dx" I get this message 'ready - started server on 0.0.0.0:3000, url: http://localhost:3000' which indicates that some variable is not being set with the proper URL. Furthermore, when I try to interact with the app I get an ECONNREFUSED error. Thanks in advance

Hey Samuel, you might be missing NEXTAUTH_URL? If you can post the full error message, that would help us know what’s up

Hey @Agusti, Sorry that question was pretty vague. Here's a bit more detail. Currently my .env is configured as follows (with domain replaced with my actual domain). I don't believe I'm missing the NEXTAUTH_URL but I could be misconfiguring it.
