Original GitHub issue: https://github.com/netbirdio/netbird/issues/5347

Is your feature request related to a problem? Please describe.
I am testing the new functionality of reverse proxy. I have several internal endpoints, which do not have a fqdn, like https://10.230.10.2.
When trying to reverse proxy this endpoints, I get 502 error:

2026-02-16T15:22:51Z WARN proxy/internal/proxy/reverseproxy.go:297: proxy error: request_id=d69jciu7k84s7389nslg client_ip=10.1.130.197 method=GET host=test.netbird-proxy.examplw.com path=/ status=502 title="Connection Error" err=tls: failed to verify certificate: x509: certificate signed by unknown authority

Describe the solution you'd like
I would like the option to add a new env variable, something like NB_PROXY_INSECURE_SKIP_VERIFY, which alows insecure connection to internal resources.

@jeditec commented on GitHub (Feb 16, 2026):

This feature will be really useful, In my scenario I have most of the services hosted in the netbird server itself as it is the most powerful server I have, I have several services hosted that require https itself and I am facing the issue of seeing error like:

netbird-proxy | 2026-02-14T08:44:01Z WARN proxy/internal/proxy/reverseproxy.go:297: proxy error: request_id=d683bkcepbkc73e9bs20 client_ip=172.30.0.10 method=GET host=100.88.113.135:10443 path=/ status=502 title="Connection Error" err=tls: failed to verify certificate: x509: certificate is valid for 127.0.0.1, not 100.88.113.135

My only workaround is using http services (port 80) when possible but some of the services require https as http just redirects to https, making many of my docker containers not reachable. So having a skip tls verification will be a great option to have.

I upvote this request.

Yes, too for proxmox that use https port with auto generated certificate

+1 most internal self-hosted resources usually have generated self-signed/invalid certs.

+1 from me. I have valid certs for all my internal stuff as I use a local traefik already, but I STILL get this error because Proxy terminates TLS.
