Comment 1 Nicolas Fella 2019-01-31 09:39:13 UTC 
Looks like it's choking on some certificate stuff. Can you check if running 'rm -r ~/.config/kdeconnect/' resolves it?
Comment 2 Carlos Massucci 2019-01-31 20:52:31 UTC 
Worked. I will restart the system to make sure everything is allright.
Comment 3 Carlos Massucci 2019-01-31 20:56:38 UTC 
Yeah Perfect.
Comment 4 Carlos Massucci 2019-01-31 20:57:45 UTC 
Should I mark this as resolved/fixed?
(I am very new to this plataform)
