Key based auth not working

[tyler-rt]

If I delete the password: "password" line of the yml per README instructions, I get the following error:

2025/09/05 15:51:04 prepare cluster: run task ImportArtifactTask: create remote runner for node [node2]: establish connection to 10.143.0.120:22: ssh: handshake failed: ssh: unable to authenticate, attempted methods [none], no supported methods remain

Is there any way to use pubkey based authentication for SSH?

The m3fs cluster tool cannot authenticate to the dx15 node, even though manual SSH works fine.
