Description Massimiliano L 2021-04-16 16:09:14 UTC

SUMMARY
From time to time FISH access to a remote server stops working with the dolphin status bar hanging on "Connecting..." / "Loading folder...". When this happens, it becomes impossible to reconnect. There is no timeout and the user is not prompted with any log about the backend. SSH access to the same machine works fine.

STEPS TO REPRODUCE
Use fish for some time until it stops working (sorry, I do not find a specific trigger).

OBSERVED RESULT
Unable to connect to servers through FISH.

EXPECTED RESULT
There should be no situation in which the protocol "hangs" indefinitely.

It seems to me the KIO sftp is more stable, although FISH has been reported to be faster in the past I do not notice performance issues with sftp so far.
