I’m using the newest version of syncthing now on a second Computer. After creating folders to sync, I realized that I made a mistake and I wanted to delete the wrong folder, but it isn’t possible. I get always an Error of Connection and the syncthing surface in the browser broke down. I tried it with different browsers (Edge, Chrome, Firefox) but always the same error. Even when I tried to delete the folder with the Windows-Tool SyncTrayzor, the same error and a I have to restart Syncthing.
I checked also old (closed) topics but without finding a solution.
