I’m using Duplicacy WEB as a docker container in Unraid
I’m trying to set up a SFTP backup storage against a QNAP Server:
But when trying to list the Directory, I get this error:
Failed to create the sftp client: ssh: handshake failed: ssh: unable to authenticate, attempted methods [none publickey], no supported methods remain
What am I doing wrong?
I have also installed Duplicacy CLI on the Unraid Host OS, and there it works with no problems, the key works at least.
What could be wrong?
I have a similar issue on a QNAP server that works fine from unraid. But when I try to access it from Duplicacy Web Edition on Mac I get Failed to create the sftp client: dial tcp 192.168.0.50:22: connect: connection refused
This is a different error. The first one is cypher selection failure, yours is connection failure. Check firewall logs and server logs for evidence of why was the connection rejected. Attempt to connect to it manually from the same host/contianer
For the Mac Web Edition case, I’d test from the Mac itself, not from Unraid: ssh -p 22 user@192.168.0.50 (or the same port Duplicacy uses). Connection refused usually means nothing is listening on that IP/port from that client, or QNAP/firewall only allows a different interface/subnet. If SSH works from Unraid but not the Mac, compare QNAP allow/deny lists and whether the Web UI is pointing at the right IP.
