SSH Handshake Failed

Questions / Help
1

I’ve just signed up to Fly, trying to deploy a simple rack app.
I’ve run fly launch and my app is running. I need to run a DB migration so when I try and fly ssh console I get the following:

Connecting to [redacted]... complete
Error error connecting to SSH server: ssh: handshake failed: ssh: unable to authenticate, attempted methods [none publickey], no supported methods remain

os: macOS Ventura 13.0.1
Fly version: fly v0.0.431 darwin/amd64 Commit: eeef66af BuildDate: 2022-11-13T17:11:38Z

Should be resolved now.

Looking into a more permanent solution.

Just deployed an app following these instructions and hit the same error.

You don’t seem to have any apps. Are you sure you followed the instructions?

5

The app is under a work account.

Oh I see.

Can you give us the organization name / slug or an app name where this broke for you?

If you could also provide what error you got, that could help. I can try to find the affected org / app / server with that information.

Thanks, the organization slug is alive-tech. The command appears to have started working now without me changing anything. Here’s what I see:
