What's the problem 🤔

I can't connect Gluetun to Nordvpn using Wireguard.

I get this error :
2023-09-30T06:56:22Z ERROR VPN settings: Wireguard settings: private key is not valid: wgtypes: incorrect key size: 48

My docker-compose :

version: "3"
services:
  gluetun:
    image: qmcgaw/gluetun
    container_name: gluetun
    cap_add:
      - NET_ADMIN
    ports:
      - 9696:9696/tcp
    volumes:
      - /media/SD/appdata/gluetun:/gluetun
    environment:
      - VPN_SERVICE_PROVIDER=nordvpn
      - VPN_TYPE=wireguard 
      - WIREGUARD_PRIVATE_KEY=MYNORDVPN_TOKEN_ON_64CHAR
      - SERVER_COUNTRIES=France

For "WIREGUARD_PRIVATE_KEY", I used my nordvpn token, on 64 char that I got on Nordvpn website :

I also tried in "run" mode :

docker run -it --rm --cap-add=NET_ADMIN -e VPN_SERVICE_PROVIDER=nordvpn \
-e VPN_TYPE=wireguard \
-e WIREGUARD_PRIVATE_KEY=MYNORDVPN_TOKEN_ON_64CHAR \
-e SERVER_COUNTRIES=Netherlands qmcgaw/gluetun

Same result :

It's working with OpenVPN.

See qdm12/gluetun-wiki#15 (comment)

The wireguard private key isn't your nordvpn token, it's usually 44 characters not 48.

Thanks for your answer.

The problem I don't see how to retrieve the private key over the web interface under manual setup

All I can get is service id / service pass and generate a new Token.

I found it following this guide :
https://gist.github.com/bluewalk/7b3db071c488c82c604baf76a42eaad3

sudo apt-get install wireguard

Then connect to Nordvpn with the client on Nordlynx protocol.

Then :
sudo wg show nordlynx private-key

Maybe it's worth it to add that to the wiki.

Does this private-key expires?
