hi i'm running Mullvad with Gluetun inside a Kubernetes cluster. The first time I set things up, port forwarding worked and I confirmed it via

curl https://am.i.mullvad.net/port/XXXXX  # port number

however, the port somehow got deleted off my account and ever since then, I have never been able to successfully set up port-forwarding again. I have tried with several different port numbers, but always fail the port check API. Is there a way I debug the issue more granularly? The port is in the same city as my exit city. To summarize, VPN works but not port-forwarding.

Configuration Here is the Kubernetes spec for my Gluetun container.
