Gluetun HTTP Proxy - Proxy-Authorization header not found from... (IP address of docker network)

[demongoggle 0]

I've recently moved to AirVPN for the port forwarding feature. I've successfully gotten Gluetun setup with the VPN and port forwarding services, but I get a message every time the proxy is used.

The log shows- "Proxy-Authorization header not found from 172.xx.x.x:xxxxx". It lists the IP address of my docker network, but the port changes every pull. I've tested the proxy through a desktop web browser using FoxyProxy, and it's showing the correct VPN IP but still shows the same log note.

Is this normal? I've attempted NUMEROUS setting adjustments, but can't seem to get rid of it.
