PSA: error status 2 false positives

[lunosdev]

This is just a public service announcement for anyone who might encounter this error. TLDR check that your transmission app is working, not only the logs!

After ~10 hours tinkering with a new docker-compose setup, I realized that the following error is often thrown unnecessarily:
ERROR: Linux route add command failed: external program exited with error status: 2

I've used this container in a basic docker-compose implementation for 2 years without issue, so I believe it's related to something in my new setup:

• moved to an externally defined network (vs defined within compose)
• added google oauth
• added traefik reverse proxy with transmission-vpn behind it using http router & cloudflare dns/certs
• *arrs using network_mode of transmission-vpn container

To be clear, the error was thrown accurately at first. After a while I stopped checking the url and only looking at the logs... later to find out transmission was working, other apps connecting to it, etc, even after seeing the error in the logs.
