Description Jiri Prchal 2023-10-25 12:17:13 UTC

Either krusader or dolphin doesn't connect to sftp, it says "Authentication failed". Using keys, confugured in ~/.ssh/config, ssh on terminal connnects, but krusader don't.
Regardless I configured:
 	ControlMaster auto
	ControlPath /tmp/ssh-%r@%h:%p
	ControlPersist 1h
to reuse connection and while terminal is connected.

At server I see that it uses wrong keys:

Where it takes the rsa or ecdsa from?
