Originally created by @mrb3n813 on GitHub (May 15, 2025).

I am attempting to use the built-in netbird SSH but receive this error when trying to connect to a peer:

Error: ssh: handshake failed: ssh: unable to authenticate, attempted methods [none publickey], no supported methods remain
Couldn't connect. Please check the connection status or if the ssh server is enabled on the other peer
You can verify the connection by running:

 netbird status

Error: ssh: handshake failed: ssh: unable to authenticate, attempted methods [none publickey], no supported methods remain

I allowed SSH for the peer in the management console then did: netbird up --allow-server-ssh on the peer

I am using the latest Netbird self-hosted version, set up using the one-liner quick start command.

I have not been able to find any similar issues. Is there a configuration step I am missing with the self-hosted version of Netbird?

Since upgrade netbird client on one of my workstations, I am facing the same issue.

Could you please explain why it was closed without comment, or what can I do to debug this?
