Cannot find/connect to the server of my friends

[Nobody96]

Hi there,

 

since the May the 8th I am having troubles hosting a multiplayer server. I also have issues connecting to the servers of my friends. Others are able to connect to these servers just fine, therefore it must be an issue on my side. I haven't changed anything on my configuration though and the issue didn't got better or worse through the updates.

 

Issues:

 

I cannot join the servers hosted by my friends. We tried two machines, everyone else was able to connect. I couldn't find the server in the server browser and when I connected via manual ip, I got a 'connection interrupted'.

 

When I am hosting a server, my friends do not find my server in the server list and when they connect manually via ip the mission loads, but as soon as they are finished loading the mission, the connection gets interrupted.

 

The list of servers I am able to see in the server browser is very short. I am getting currently about 25 entries were as my friends regularly have about 50-60 servers in that list

 

Things I tried so far

 

Checked if the ports are open on my and my friends site via nmap. - positive

Checked if a connection is possible via telnet. - positive

Checked if packages are transmitted after a connection is established but also after a connection refused displayed via wireshark. -positive

Checked if my network configuration is working or if a firewall is preventing the connection. -positive ( I am working as a devop, my friends also very qualified and rechecked my config and the configuration was working previously and hasen't changed)

Switched from 'Lan' to ADSL, to Modem speed on the server and the client side.

Hosting with 'Internet' and 'Lan' setting enabled

Reinstalled DCS

Reinstalled DCS and wiped my config from 'Saved Games'

Reinstalled DCS, removed all registry entries I could find and removed my config from 'Saved Games'

All of the above, plus I uninstalled all the Mircosoft Redistributable and Mircosoft Visual C stuff and got it reinstalled from the DCS setup.

 

I have run out of ideas to check. I cannot fly with my friends anymore, something I enjoyed for the last 3 years. I would love to get some hints or help.

 

so long

I had a similar issue and it ended up being two things:

 

1. I didn't have my router ports forwarded correctly and found this useful guide Port Forwarding Help Guide

 

2. I was using a VPN program call Comodo as a workaround initially when I got this game, however once I sorted out the Port forwarding issue, I forgot to disable Comodo. I disabled Comodo Unite adapter LAN connection through Control Panel > Network and Sharing Center > Change adapter settings.

 

After that was done, people could see my hosted Internet missions in the DCS World lobby and connect/play successfully.

 

Good luck

Another frequent issue is version error... Make sure you're running the same version on all modules on client and server.

 

Also disregard any speed setting other than LAN- on both sides.
