Why would I be able to access a remote (non-localhost) server on LAN via port 3000 and not 8080. Firewall off on all (Win) devices, even though port 3000 didnt require that

2019年5月16日 · Same issue for me, triggered by running Vue dev server on port 3000. In my case, I wanted to browse to localhost:3000 via a custom host-mapped local domain name (e.g. mysite.dev) instead, so I incorrectly set my local Apache configuration to listen on 0.0.0.0:3000 and defined <VirtualHost *:3000>.
