State machine error being thrown in replication sync [Xamarin

Mobile
1

I’m getting a strange intermittent problem when the replicators attempt to start. Running CBL 1.3.1 in Visual Studio 2015 with Xamarin Android (Latest).

0:] INFO) SYNC (Replication): [5] 2016-11-25 10:12:18.993+08:00 Attempting to start pusher (fa737a60-d160-4902-bfa9-2a0e84f50fbe)
[0:] ERROR) SYNC (Replication): [10] 2016-11-25 10:12:19.023+08:00 State machine error:

This doesn’t happen every time, maybe 50%. The replicator never recovers after this. Any help is appreciated, thanks.

Full stack trace:

having this same issue, anyone know what to do?

you can use a build from the CI server or if you are curious about the fix it just involves replacing WebRequestHandler with HttpClientHandler and not using ReadWriteTimeout
