Gateway page not loading via OpenVpn

So I setup OpenVpn Server:

Home Network -> pfSense OpenVpn (hosted in home network) -> VPN Tunnel Network.

Ignition Gateway is on Home Network.
My phone/laptop on Tunnel Network via 5G data.

From Tunnel Network, I can access the sites/servers on home network.
But when I try access 8043. Seems the page would not load..

Trying to check, if somehow there is gateway settings that need to be enabled.
Hmm, maybe something to do with Cipher Settings? As I use legacy one. :thinking:

Edit 1:
changing Cipher does not work.
:thinking: I know.. probably the Certificates stuff..

Port 8043 is the HTTPS port. You must have SSL properly configured, typically with publicly valid certificate, for that to be usable remotely.
