Using Caddy with Express VPN

[The_Spartan (Jake Marnatti)]

1. Caddy version (caddy version): 2.1.1

2. How I run Caddy:

I use Caddy to create a reverse proxy for Ombi. I have my own domain and setup a DNS query for ombi.mydomain.nl

a. System environment:

I use Windows 10 Home to run Caddy for Ombi.

d. My complete Caddyfile or JSON config:

ombi.mydomain.nl {
reverse_proxy 127.0.0.1:38084
}

3. The problem I’m having:

I use Deluge as a torrent client and have Sonarr, Radarr and Jackett installed as well. I tried to use the split tunneling feature on ExpressVPN to prevent Ombi and Caddy from being encrypted in the VPN. When the VPN is off, everything works as intended. When I start the VPN, Caddy starts, but i get a constant loading from the borwser trying to access Ombi at my domain.

I also cannot seem to to get Caddy to properly start with Windows.

5. What I already tried:

I have tried changing applications and managing the split tunneling feature with Express VPN.

I tried using NSSM and a .bat file to start Caddy.

Here is the error I keep getting when I turn on the VPN even though Caddy and Ombi and Dynu IP are all set to NOT use the VPN. I also have a windows firewall rule set to accept all 80 and 443 port connections. And I have the VPN set to allow all LAN connections.
