Caddy v2 Reverse proxy returns blank page

Well…nothing. Looks like the outbound connections to other machines on the LAN are being blocked.

Funnily enough, if I try curl https://google.com I get the page contents.

So I guess it’s one of these two:

  • Other machines on the network are blocking connections (weird, because it was working just fine)
  • My raspi has some iptables config that is blocking outbound connections to local network

Any ideas on how to proceed? I am a bit lost…
