Hey there,
I just tried to start rclone v1.53.1 on Windows 10/amd64 with following command:
./rclone rcd --rc-web-gui
2020/11/29 21:03:25 NOTICE: Web GUI exists. Update skipped.
2020/11/29 21:03:25 NOTICE: Serving Web GUI
2020/11/29 21:03:25 NOTICE: Serving remote control on http://127.0.0.1:5572/
Now, rclone gui wants a http-Login. I don't know, what to insert. Nothing works (even not the randomly shown pw by adding -vv)
It is the second time I was trying to start rclone gui. The first time I just configured. I found that the latest profile I created was not displayed in the GUI. That's why I decided to restart rclone GUI.
But now I have the login problem. Really annoying. I have not set / changed anything that would activate a login query.
