Hi Michael, thank you for the reply.
Currently we have each of those ports open but are still running into issues connecting. Opening it up completely allows it to start working, but due to our network security requirements, that’s not a viable solution for us. Is there a range of IPs or hostnames you could provide that we would need to open up access to?
Re: using infra branch 5.5, we found it to be a lot more stable and consistent than previous infra releases. I confirmed we are still having issues with Pixel Streaming on UE5.5 as well, which confirms it is a networking issue vs a UE version issue.
Best,
Drew
