If you can't open the port, try disabling whatever firewall that might be blocking it.

why would that mention port 3074, the only thing there would be the used-later-on-to-my-knowledge STUN servers, which are irrelevant to the *local* DW server ._.

Don't ask me why, but I tested here properly with a computer having that issue, before posting the solution. Toggling port 3074 on windows firewall was toggling the problem aswell. If either TCP or UDP rule for port 3074 was disabled on windows firewall, I would get that problem on that computer.

And seems that it worked for more people here on the forum.

There's more to be told about that stun communication... I remember my T5 tests. While I was connecting and disconnecting my network from the internet, the servers would be unranked. But if the internet was always on, or when I got to the LAN party where there was no internet at all, the servers were ranked.

The only thing changing was stun communication. So, according to my tests, there's something there that will only work if a clear connection is stablished, or if no connection exists at all.

Sounds weird, but that's the results of my tests on stun communication.

If either TCP or UDP rule for port 3074 was disabled on windows firewall, I would get that problem on that computer.

ah, so STUN is mandatory on IW5. good to know.

Wait, you said you pressed on ''Play''. You need to click on ''Servers'' to play.

Wait, you said you pressed on ''Play''. You need to click on ''Servers'' to play.

"Connectin to online services" issue happens on both options the same way.

Yes ''online services''. He said the ''server'' which happens like so: ''The connection to the IWNet server has been interupted''. He could have just misstyped the ''error'' ;p

it keeps connecting for 2 min or so and then says

That matchmaking error message is instant. "Connecting to online services" can last long though.

Let's just wait for him to reply ;p

 

OP, are you using ''Play'' or are you using ''Servers'' ?

again, its highly unlikely that someone mistyped an error ._.

(p.s.: yeah, we'll get back on-topic when OP replies)

Unlikely, yet still possible ;p

Well, atleast you agree

Thx for all of u going to try some stuf but my english is not te best as u have seen

but when i push server or play both give the error after waiting like 2 min

it aint instant

the error says: the call of duty modern warfare 3 is not availeble please try aggin later or go to and the website of callduty.

i just instaled the game and didnt do anything either

PS sorry for the late reaction i was working

No problem

Your problem is that some firewall is blocking port 3074 (TCP and UDP)

Disable the firewalls or create TCP and UDP exception rules for port 3074

and where can i do that ?

Just disable your firewall
