The Dreaded "Cannot create connection to host"

Hi there,

New member looking to take on FSX in multiplayer mode but stumbling at the first hurdle. I've tried absolutely everything I can think of other than completely wiping my entire system and starting again (really don't want to do that).

So, here is what I have so far...

Windows Firewall - Disabled
Avast Firewall - Disabled
Router - Set to DMZ for my IP.
(I know this is unsafe, I was troubleshooting)

Network Settings:
Port Range - 6112-6122 (I've tried 6112-6112 as others had success)
Voice Compression - I cannot change this from 24.000kbps
Voice communication - Enabled
Connection timeout - 90
Keep alive - 15

I then select LAN, type in my name, click sign in then click "Connect Directly". I type in one of the current IP connects which at the moment is I click "Find Sessions" but I immediately get "Cannot create connection to host".

I've tried completely uninstalling FSX which made no difference. I'm not really sure what else to try.

I may have answered my own question. After typing in "FSX steam and FSOPEN" I have found a few links where it's stated that the SE of FSX doesn't work with FSOpen. That's a bit of a bummer as I liked the idea of the community here. Surprised not to see that mentioned in the quick setup guide though. Has something changed to allow it now?

Sorry Scott, I can't support steam edition as dovetail games changed how multiplayer worked and don't want to share the information with anyone.

If you replace the api.dll ; fsui.dll and main.dll in your FSX-Steam folder with the api.dll, fsui.dll an main.dll from the "old" FSX (for example from the DVD), you can use FS-Open Multiplayer in the FSX-Steam Edition.

Is this true Bjorn? Would love this to be true. Anyone want to test it?

We had one User here at the GFS Server who used this method, I can´t test it myself because I don´t own FSX-Steam Edition.

Dave - just tried what Bjorn wrote in his post. It does not work. If you replace the api, fsui and main dll files FSX Steam version will crash. It was worth a try

Thought it was too good to be true, thanks for testing David
