Disconnected exception on connect?

[LigmaLlama]

I've had this for over a month now, thought an update would fix it, but nope... what the honest F*** i can't play any matches, play button is grey? Well a potential fix and fixes have been listed for those that may be having this issue, after tons of research this is actually not an easy one to figure out how to resolve online, even youtubing this you'll probably find nothing!

Tuns out that's not related to IP I discovered, (Maybe false in some perspective) It appears that it's a common "ANTIVIRUS" game update that ends up listing the game as a virus or doesn't completely get set as accepted by a antivirus, after checking my antiviruses i allowed it access via the antivirus, and made sure that anything it blocked (files) were removed from the block! - My antivirus for example is bitdefender

--------------------------------
Another option is that it could be an ISP or Router block (you'll more than likely end up with a different code if this is the case), now there's a few workarounds if this is the case, I'll list a few:

1) Some network providers will allow you to type your IP into your browser and it'll take you to your router/hub set up page that'll allow you to edit and adjust ports and firewalls, and see if anything is getting blocked. Please research on your own devices to find out what it is, or how to adjust things personally.

2) Another option is to contact your ISP

3) close game, open cmd (In windows search bar) type "CMD" right click it and run as administrator and then type or copy and paste: ipconfig /flushdns (it will clear dns cache) make sure to press enter after typing

Решается через vpn. Победил проблему так

I'm not sure if this is still relevant to people but I had the same problem but it persisted across certain games, for instance i wasn't able to connect to space marine lobbies. my fix was to disable something called cFosSpeed in your internet port options or fully uninstall it.
I found this problem happened on a fresh install of windows 11 and I believe its something to do with how it prioritises different packets when sending requests to servers. Keep in mind that I'm using Ethernet and the solution may be different for wifi users.

1. open control panel
2. navigate to network and internet
3. navigate to network and sharing centre
4. on the left side of the window click on change adapter settings. you should see all your available internet and Bluetooth connections.
5. right click on the connection type your using (for me it was Ethernet and it should show the name of your current connection, if you have a lot the name should match what is written on the back of your router)
6. click properties, make sure you are in networking
7. find and disable cFosSpeed, it may also be called NDIS 6
I would be careful with uninstalling it because it could cause other problems. cFosSpeed is primarily used for VoIP so your pc with prioritise VoIP packages over other packages.
8. click ok/save and restart.
9. and there we go should be fixed

Note: this includes other games that use peer to peer connection
