I cannot get this PC to (stay) connect to Sync - Every time I log in, I get an email, but within seconds (sometimes instantly, sometimes after a few minutes) I get the yellow warning triangle with the "reconnect to sync" message. I have tried the steps in another post: delete the signedInUser.json file in the Firefox profile folder and delete the Weave folder But that hasn't worked. I have uploaded a sync.log https://pastebin.com/AqSgha95
