I searched if anyone is facing this problem, I did not find anything.
I followed the Docs and SpaceInvaderOne video to install the plugin.
Even the flash backup does not work and show this message:
Needless to say that the remote access did not work as well, and I did everything according to the Docs, but this is another problem and I will post it later. At the moment, I want to solve at least the flash backup.
