d7d78dd created the issue

I can edit files in only one location on server. If I open next one from different folder (on the same server), the other files either stop writing or close at all (without saving changes!).
I also use a second computer with Windows, where there are no such problems at all.

A less critical issue is constantly watching "Directory listing failed" / "Upload failed". Clicing "Try again" usually helps.
The connection refreshes itself automaticly on Windows.

I use Brackets code editor in both cases (MacOS 10.15.7 / Windows 10). I've also checked another editor but tested persisted.

I have tried to find an alternative to Cyberduck but none of the other apps suit me this way.
So I really hope to fix the problem soon.
