Service Fabric can't connect to guest executable on UDP (Unreal Engine Server)

问题

I'm trying to deploy Unreal Server guest executable to Service Fabric. I've been fallowing this blog post:

http://haishibai.blogspot.com/2017/03/setting-up-highly-available-minecraft.html

Except I'm not using containers and use Windows based service.

On local cluster everything works. I can connect from client to deployed server.

When trying to connect to remote server, I can't connect to it.

When looking at my service fabric managment page It seems like my server process is working (it have proper process id).

In my LoadBalancing service I have port forwarding on UDP/7777, though HealthProbes are on TCP (there is no option to select UDP, I don't know if that mnatter).

Here Is my ServiceManifest:

1.You seem to be missing the service endpoint configuration.

<Resources>
  <Endpoints>
    <!-- This endpoint is used by the communication listener to obtain the port on which to 
         listen. Please note that if your service is partitioned, this port is shared with 
         replicas of different partitions that are placed in your code. -->
    <Endpoint Name="ServiceEndpoint" Port="7777" />
  </Endpoints>
</Resources>

UDP isn't supported for probes on the load balancer. So, expose a second service endpoint that uses tcp, just as a health endpoint.
