So I was using Google cloud buckets to host my site, I figured out SSL Is impossible doing that so I tried app engine and that just got really complicated really fast so I tried firebase and it seems the best, however I have my main site (https://example.com) and my development build of the site with an auth login for me and my devs (https://staging.example.com). I have 2 different firebase projects one for the main site and another for the subdomain, however I first connected the subdomain one and it got an SSL cert and said connected in like 2 seconds, however I did the same for my main site and it's been stuck on pending all day now. I read somewhere that it can't do a subdomain and a normal site because of some SNI thing but if you can't enable SSL on a domain and a subdomain that's a pretty bad system imo. I use Google Domains for my domain and there are A records for the normal domain and subdomain pointing to firebase.
Thanks to anyone with any clarification.
Turns out I just had to wait for the certificate to be made, I was just confused as to why one domain took seconds to make it and the subdomain took almost a day so I thought something was wrong.
