Hi! A group of us have been trying to use SCX but despite having it connected, near each other, and on the same frequencies, we never see anyone else in the "on frequency" list. Any ideas on how to troubleshoot this? We have opened ports 7600 and 9988 on our routers, ensured the Firewall allowed the connection, etc. but can't seem to figure it out. Thanks!
Here's my log file:

Hi Kip,
There's a few errors there. The NAT one looks to be the main problem. Leave it with me and I'll see if I can reproduce it. Although I am very short on time at the moment, so I'm afraid it might take me a while to get to it.
What Sims are you using out of interest?

Thanks! MSFS 2024 with FSUIPC. We have FSUIPC ticked in SCX because installing the old SimConnect versions seems like it might make FS24 unstable, so trying to avoid doing that.
We've also tried connecting to a private shared host without any luck. This log also represents me hitting the PWR button a few times to reconnect to see if it helped.
