Description
After the signaling server and the program are successfully connected and all settings are correct, the background screen still cannot be loaded on the web page. This issue has been present since the UE5 version. The reason is that in version 5.4, the IP address can be manually modified (specifically, the:SetPublicIP function). After the update in version 5.5, the IP address is automatically obtained from the common.bat file. This is the main cause of the problem. When there are restrictions of NAT type, and the network environment (such as enterprise networks, campus networks, or certain home routers) blocks the STUN/TURN protocols, and the firewall/UDP port is blocked, WebRTC cannot establish a connection. Even if all steps are correct, the screen still cannot be loaded. Currently, my solution is to modify the:SetPublicIP function in common.bat to manually set the IP address. This will work. I hope the team can solve this problem with a more convenient and stable technical solution. Thank you.
