Created attachment 109990 [details] Previously working config After updating from Kubuntu 17.04 to Kubuntu 17.10 Dolphin's sftp broke, with the same configuration I'm no longer able to access the share. The only message I get is "Authentication failed" but I could previously connect just fine and ssh still works just fine.

I cannot reproduce this issue with Dolphin 19.04. Do you still experience this problem with a newer version of Dolphin? SYSTEM INFO Operating System: KDE neon Testing Edition KDE Plasma Version: 5.15.80 KDE Frameworks Version: 5.58.0 Qt Version: 5.12.0 Kernel Version: 4.18.0-18-generic
I switched from ssh-agent to specifying the identity file in ssh config and of course a year has passed and everything has been updated so who knows if this specific issue is fixed - I just no longer have the problem.
