Describe the problem

When following the Multiple proxy instances guide, I have came across multiple issues, one of them I haven't been able to solve.

Issue with docker-compose.yml still using image: traefik:v3.4 which is incompatible with latest docker (API errors), resolved with using image: traefik:v3.6 like the netbird-server uses
netbird-proxy not able to connect to management:

netbird-proxy  | 2026-05-02T18:57:10.661140094Z 2026-05-02T18:57:10.660Z WARN proxy/server.go:988: management connection failed, retrying in 1.179s: mapping stream: receive msg: rpc error: code = Unimplemented desc = unexpected HTTP status code received from server: 404 (Not Found); transport: received unexpected content-type "text/html"
netbird-proxy  | 2026-05-02T18:57:11.965957532Z 2026-05-02T18:57:11.965Z WARN proxy/server.go:988: management connection failed, retrying in 1.45s: mapping stream: receive msg: rpc error: code = Unimplemented desc = unexpected HTTP status code received from server: 404 (Not Found); transport: received unexpected content-type "text/html"

I have triple checked the DNS settings and I can properly connect to management interface via browser.

I haven't figured out the problem here yet, but seems like the traefik from getting-started.sh is not exposing gRPC properly or proxy.env is incorrect in the documentation.

Please note that I haven't used Traefik before, so i might be completely wrong and be fully my mistake

To Reproduce

Run the getting-started.sh with built-in traefik on machine A
Follow the Multiple proxy instances guide on machine B
Watch logs on machine B

Expected behavior
Secondary proxy successfully connecting with the management

Are you using NetBird Cloud?
No, self-hosted.

NetBird version
Installed today: 0.70.4, netbird-proxy:latest

Is any other VPN software installed?
No.

Have you tried these troubleshooting steps?

Reviewed client troubleshooting (if applicable)
Checked for newer NetBird versions
Searched for similar issues on GitHub (including closed ones)
Restarted the NetBird client
Disabled other VPN software
Checked firewall settings
