When you captured that log, were you on your local network with the iOS device, or outside of it?
The Timeout error when connecting to your LAN IP indicates that your computer probably has a Firewall that is silently dropping the connection sent by JRemote. The Firewall settings probably weren't preserved through the upgrade. You can test this by disabling the Windows firewall, or whatever third party software suite you have installed. Windows Firewall instructions haven't changed for Windows 10, I believe:

allow inbound TCP traffic on port 52199.
If you are using a third-party suite, often disabling them isn't enough, and the best test is to uninstall it (temporarily) to see if the issue goes away. If so, then you know the cause and can look at how you create exceptions in it.
If you are outside of your local network with the iOS device (on cellular or away from home), then it looks like your home router is refusing the connection (which is odd, it should probably also silently drop, but whatever).

The connection refused could be an incorrect password (I don't know for sure how MC responds in this case).
