I am using Unreal Engine 5.5.4 and implementing multiplayer with the Epic Online Service as a host. I can connect to the lobby, connect to the session, and have voice chat.
However, after that, the client cannot move to the host’s level using ClientTravel (host IP address).
The following message appears in the log:
Initial Connect Diagnostics: Sent ‘10’ packets in last ‘10.009188’ seconds, no packets received yet.
If I specify a local IP address and run OpenLevel (host IP address: 7777), I can move to the host’s level.
There may be restrictions on port 7777 on my home network, but I cannot open ports on my router every time.
I would like to know if there is a way to move to the host’s level by going through the NAT on the Epic Online Service.
