Just a few comments on this. Most people aren’t “lazy”, they just understand that the effort to run a bare repository is greater than basically any other solution. Also your incompatible features list implies that other git repo sites (gitlab, codecommit, bitbucket, etc) don’t have their own form of proprietary stuff that you have to learn. In fact the newest version of gitlab actually changes their web ide into vscode web, because of the obvious, it is much better than their old ide.
Since it sounds like this is your home router since you mentioned you use Comcast. If you are testing the site from within your network using your external ip then you are possibly running into a loop back block. Comcast does not allow traffic that originates from within your network back into your network.
Try the ip/site from a Hotspot and that might work.
