I have been using this several years, after the last update it has become totally unreliable. About 3-4 times a day it will just stop working and all the folders show up as Unknown on the GUI. There are no hardware issues and it has never happened before this last update.
Does the problem look similar to Syncthing unresponsive with "wsarecv: An existing connection was forcibly closed by the remote host"? Are you able to check the log if it’s filled with the same entries as reported in the other topic?
