500 Can not connect to domen: 443 (connect: Network is unreachable); Client-Warning: Internal response

Your requests never go outside of your local network if at all. Maybe you need to use a proxy like your browser does, or you have two routes and the name resolution ping-pongs between a working network route and some other network route.

Maybe the name resolution itself is wonky for some domain names.
