Unable to host a session, guests always get timed out, IL2 4.11.1
After years and years of hosting flights, literally thousands of flights, now when I host, the game starts up normally, but guests always get timed out.
I believe the problem must be with some setting in Windows.
And it is not a Hyperlobby issue, as the timeout also occurs when I host in IL2 multiplay, that is not going through Hyperlobby.
The history is that I had to reinstall [parallel install] Windows after a Windows repair failed, hanging up halfway through.
After the Windows parallel install I copied and pasted IL2 4.11.1 [fully patched of course] to my pc from an external hard drive where I had saved it.
IL2 appears to work perfectly in all aspects, including joining other rooms/servers through Hyperlobby, with the one exception; That is, I cannot successfully host my own room. the guest always getting timed out.
I am using XP 64 bit, and Windows security essentials for anti virus, BUT the problem persists EVEN WITH THE FIREWALL TURNED OFF.
I believe I have port 21000 allowed in Windows for both Hyperlobby and for IL2, but feel sure I'm missing some little deatil somewhere.
