Networking is always fun to debug.. haha. I tried to replicate your issue but was unable to. Are you using docker, kubernetes or something else? Would be helpful if you could post your docker-compose.yml, kubernetes object manifests or other relevant config.

Found the issue '^-^
UFW also blocks traffic between docker and host.
I had to add these rules
ufw allow proto tcp from 172.16.0.0/12 to 172.16.0.0/12 port 80
ufw allow proto tcp from 172.16.0.0/12 to 172.16.0.0/12 port 443
If you are using openvpn this env may be a good thing to try. It may need adjusted though.
OPENVPN_MSSFIX='1350'
Same problem.
I tried a few values and the same, ping works but curl doesn't.
