does not work

Hello

I used syncthing (debian linx) in the local network for a long time, all ok.

I made some changes and stopped working using the GUI.

I ran on [apt-get purge syncthing] and then I reinstalled everything again on the two devices on the local network but it doesn’t work anymore.

Here is the message:

2019-11-28 16:32:21: Failed to lower process priority: set niceness: operation not permitted

What to do? Thanks

That message is just a warning, it has no effect.
