If I will change owner will it have imapact for something else?
EDIT: I tried and it’s better 
Now I have this:
XYZ sync failed to setup inotify handler. Please increase inotify limits, see https://docs.syncthing.net/users/faq.html#inotify-limits
I follow link and from root account input this:
echo "fs.inotify.max_user_watches=204800" | sudo tee -a /etc/sysctl.conf
I also restart Syncthing but it didn’t help. Should I restart Dietpi also?
