I was looking at this thread but running. It is set up with 500 extra GB of storage. I have installed a vnc server to support the GUI. I am using the Ubuntu 18.04 NVIDIA RTX image on EC2 with the g4dn.xlarge instance. I used the Omniverse Echange to install Isaac Sim (2021.1.1). I have installed Omniverse (1.3.4) and set up a local Nucleus Service (2021.2.5). (I am assuming it crashes, there is no error displayed it just doesn’t open anything.) The solution to this problem is that connect to the same end point your server is listening on.When I click “Launch” in Omniverse for Isaac sim it 1/2 opens a window and then crashes immediately. So your client is trying to connect to any of the non-loopback addresses of your machine, while your server is listening only on the loopback address. This includes the public and local IP addresses of your machine (e.g. When you pass a host name to TcpClient, it will resolve it to one or more IP addresses using Dns.GetHostAddresses(hostName). ĭns.GetHostEntry(IPAddress.Loopback).HostName returns the host name of your machine. It allows the computer to communicate with itself via network protocol. This exception message says you're trying to connect to the same host ( 127.0.0.1 ), while you're stating that your server is running on a different host. The target machine actively refused it 127.0.0.1:xxx There are various architecture choices you can explore that mitigate queuing up sockets and processing them sequentially. If you wrote the server, you might have heavy processing in the accept of your client requests, and it is better moved to a separate worker-thread so your accept is always ready to receive more connection requests. ![]() Regardless of whether you can increase the server backlog, you do need retry logic in your client code, sometimes it cope with this issue as even with a long backlog the server might be receiving lots of other requests on that port at that time. If it happens occasionally, it is likely because the server has a full 'backlog'. n : Numerical display of addresses and port numbers b : Displays the executable file of a connection or listening port (requires administrator rights) In Windows operating systems, you can use the netstat services via the command line (cmd.exe).
