I keep periodically losing connection to the gateway (Ignition standard 8.3.0-beta4) when working in Designer. Seeing several UascClientMessageHandler & MulticastScheduler errors in the log. I’m working remotely and connecting to the gateway through a VPN. Could anyone confirm that it’s most likely a network issue? I also have a lot of clock drift warnings.

Multicast is unrelated (it's only used for launcher auto-discovery of gateways on the network, not used for actual client/designer connections)

`UascClientMessageHandler` is also not connected, the `Ua` there is for OPC UA. That said, "a connection was aborted by software in your host machine" seems... suspicious.

In your full logs there _are_ some client/designer related errors - new to 8.3, there's now a persistent websocket connection between the client/designer and the gateway, and there are (some) errors in that channel with the same "aborted by software in your host machine":
