Host OS

CPU arch

VPN service provider

What are you using to run the container

Portainer

What is the version of Gluetun

Running version v3.38.0 built on 2024-03-25T15:53:33.983Z (commit b3ceece)

What's the problem 🤔

EDIT: I think the issue might actually be the space between United States and Canada. Using united states,canada doesn't throw an error. Perchance this is and issue with spaces, not cases!

Using NordVPN: SERVER_COUNTRIES with United States, Canada fails
the country specified is not valid: value is not one of the possible choices: value canada, choices available are
...
Cambodia, Canada, Cayman Islands, Chile,
...
I'm using Portainer with the Environment variables section and the following does not work:

but

does work.

Could this be a Portainer-specific issue?

Anyway, the quick fix for me is to note that the comma separated list must not contain spaces between items. Perhaps this could be added to the wiki?

Everything else is great!

Thanks for the detailed issue report, I'm traveling right now so I cannot test much really, but can you try to see if the latest image (docker pull qmcgaw/gluetun) has the bug still? Settings parsing was changed, and spaces may be trimmed. Otherwise, I'll code it up to trim prefix and suffix spaces for all filter values. Better codify it than documenting it 😉

I was also traveling.

I think it's the same:
Canada, Mexico, Germany Doesn't work but
Canada,Mexico,Germany does work

Thanks for looking into this!
