I want to connect from openSUSE Leap 15.4 to a SLES15SP4 Host. Until now I use Dolphin (KDE File-Manager) and the URI fish://. This was a highly comfortable way to work with an SLES host.
I am able to use this to older SLES or other linux host without any problem. But to a new installed SLES15SP4 the connection is never established.
The host in question can by reached via ssh and scp. And I can mount a folder from this SLES15SP4 via mount.sshfs into my local filesystem.
What is needed to get the fish:// back?
