@timfoley66 I had the same issue, but found the following error:

2025-01-04T17:28:59Z ERROR creating tun device: unix opening TUN device file: operation not permitted (did you specify --device /dev/net/tun to your container command?)

I simply added the following to my docker-compose.yaml, but the same can be done via dockerfile if needed:

devices: - /dev/net/tun:/dev/net/tun

I referred to this previous bug:
