Connection Refused when port sharing local requests

[Begall]

Hopefully this makes sense. I’ve got OpenVPN Access Server 2.7.5 setup on port 443, as I have only one (Ubuntu 18.04) server and I want to access the VPN externally. As I have a number of both internal and external web services I want to use, I have used a custom port share to redirect non-openvpn traffic locally to port 4545, where an OpenResty/Nginx? instance reverse proxies my web applications.

The port-share configuration I’ve got is:
Enable=True
IP_address=127.0.0.1
Port=4545
Service=Custom

This all works fine when I access services from another device on the network, such as my phone. However, I have discovered that requests made from the same server that go across the OpenVPN port-share - even a simple curl - will fail with a connection refused. For example:

curl ​https://myservice.internal.mydomain.org results in: curl: (7) Failed to connect to my service.internal.mydomain.org port 443: Connection refused

I need these local requests to work as I have an identity service that my server is redirecting to, and I want to use my auth service hostname to SSL encrypt the requests. Possibly I have misunderstood how this should work, so maybe someone could explain what I’m missing? I’ve tried a few variants of my IP address and it hasn’t helped.
