Connecting via Putty

Issue: Server rejects connection with "Permission denied (publickey)".
Troubleshoot: Check if private key is properly selected under Connection -> SSH -> Auth. Check if you are using the correct key pair and verify that keys are actually proper pair using Puttygen.

Issue: Server rejects connection with "Disconnected: No supported authentication methods available (server sent: publickey)".
Troubleshoot: Check if private key is properly selected under Connection -> SSH -> Auth. Other possible method is to load private key into Pageant and to enable attempt authentication using Pageant under Connection -> SSH -> Auth.
Troubleshoot 2: If this didn't solve the problem, possible firewall issue, contact Leon Mei for further troubleshooting.

Connecting via MobaXterm

Connecting via x2go

Issue: Connection asks for key passphrase even if key does not need one.
Troubleshoot: Remove key selection and use "Try auto login (via SSH Agent or default SSH key)" while running Pageant with your private key imported.
