Describe the problem

I am unable to create a reverse proxy connection to any internal service when it's running on HTTPS internally. I always receive the error: Error 502 Connection Error An unexpected error occurred while connecting to the service. Please try again later. Whenever I connect over HTTP it works fine. The internal HTTPS services are using self-signed SSL certificates. Since they're internal services, valid certificates are not possible. I'm not sure whether that's related or not, but if it is perhaps add a flag / option in the GUI which ignores invalid certificates?

To Reproduce

Steps to reproduce the behavior:

  1. Create a service via HTTPS
  2. Try to access it

Expected behavior

A working reverse proxy connection

Are you using NetBird Cloud?

I'm using netbirds selfhosted control plane

NetBird version

0.66.2

Is any other VPN software installed?

No

Debug output

To help us resolve the problem, please attach the following anonymized status output

The command does not seem to be available on the server and the client isn't installed.

Create and upload a debug bundle, and share the returned file key:

netbird debug for 1m -AS -U

Uploaded files are automatically deleted after 30 days.

Alternatively, create the file only and attach it here manually:

netbird debug for 1m -AS

  • Restarted the NetBird client
  • Disabled other VPN software
  • Checked firewall settings
