Unreal Engine HTTP Server Only Works on Localhost (Cannot Bind to LAN IP)

Hello, sorry for the late response. To make this work properly, you need to add the following settings in your DefaultEngine.ini file:

[HTTPServer.Listeners]
DefaultBindAddress=any
DefaultBufferSize=32768
DefaultConnectionsBacklogSize=100
DefaultMaxConnectionsAcceptPerFrame=50
DefaultReuseAddressAndPort=true

That works for me
