URLConnection: BadResponse 429 / handshake_failure

Has anybody else been receiving the following error? It used to happen sporadically and could be fixed by restarting ConciergeServer.

It’s now happening very frequently and it’s making my Google Home integration unusable.

I am running the latest ConciergeServer (2.031) on a Synology NAS with Java 1.8.0_151.
