The community member is using a local DNS server to point multiple domains like web.in.com to their server, and using Caddy as a proxy to handle SSL/HTTPS. Another community member suggests that if the user self-hosts or subscribes to a webstudio pro plan, they can use as many custom domains as they want. However, the original poster is having trouble changing the dev URL, and has tried disabling their firewall but it's still not working. A third community member notes that this is a complex issue with certificates, and there is no simple solution.
Could something like web.in.com I already have many domains like this by using a local dns server to point the urls. And then for proxy I us Caddy which handle SSL/https.
I am self hosting I am trying to change the dev url. It's also not working I thought it was a firewall issue so I turned of the firewall still nothing.
