Home network suddenly not working shortly after update

[UnderFire]

I played for a short while the day of the Season 3 update. The next day however, I was met with an instant "Server Disconnected, your profile was signed out" on launch. Playing via steam. Doing some reading lead me down the path of doing a whole lot of things to no avail. The error has occasionally been replaced with network error code "Diver" and once with "Hueneme concord"

Before messing with networking I had tried the following:

Steam file verification. This reads that 38 files are missing, then downloads ~27MB worth of stuff, but will do exactly that over and over again. Have done many other suggested related things, terminating and running as admin, checking DLC boxes, redownloading both bits and pieces as well as the entire game.

Then I started resetting various system drivers. The only one having been done to my knowledge shortly before the issue arose being the latest Nvidia update.


Once I had exhausted those type of actions I started messing with the networking side of things.

I have tried the following:

Enable uPnp

Manual port forwarding

Switching to Google DNS

Clearing DNS and manually setting to wifi in the prompts.

Once all of this had failed, I tried to use my cellphone hotspot to test, and low and behold, the game loads, states restart required for update, restarts, loads right into the menus, and seemingly is without issue. I didn't test any further, but this is obviously much further than the home network.

Swapping back over to the home network even after successfully loading up and it's right back to all the same symptoms. I've exhausted what I can seem to find out there as far as info on fixing this goes.

Any ideas?

try to DMZ your PC ip and see if your problem remains, if it does not, restart your router and see if it fixes it.

you can try:

Type ipconfig /release and press Enter.
Type ipconfig /flushdns and press Enter.
Type ipconfig /renew and press Enter. (This will stall for a moment.)
Type netsh int ip reset and press Enter. (Don't restart yet.)
Type netsh winsock reset and press Enter.
Start a CMD PROMPT (ADMIN)
Enter this command, netsh advfirewall reset.

No change in symptom after this unfortunately.

Got the expected prompts to allow steam/mw2 through windows firewall after resetting and all that good stuff, but still goes from "Checking for updates" to "Server disconnected, profile signed out"

Tried some other stuff. Loosening router firewall restriction, verified other firewall settings, manually changed DNS server, switched to steam beta client Etc.

The only other things I got, with no real improvement were
1. Another single hueneme concord error instead of the instant kick
2. When switching the steam client, it downloaded a 300-ish MB SCR, then MW2 opened a steam window on launch, ghost-downloaded (Does not show in steam queue) around 150 MB of files, which it never had before then had to prompt me to launch. Still failing after "Checking for update".

The game always shows that I'm logged in, gets well past the connecting to servers portion etc. but never the update check.

At wit's end, wish I could just get my money back.

Verified that the game launches every time on a different network.

After launching multiple times it now regularly fails at "Loading playerstats" Instead of "Checking for update" There is a long pause and it seems to be dropping off the connection to the server at whichever point it decides to stop, but seems to be connecting to start.

that is not game related, do you have a system imagem prior that you can revert to ?

same issue is for me bro since a week only mobile data and by connecting VPN is connects to the game hope anyone gives a fix for this

My issue seems to be caused by a direct block set in place by my ISP. I've exhausted anything else it could be. Matchmaking on other games also seems to be blocked, as well as server communication on FarCry6.

In windows stting/Games - Game mode, set it to ON.
In Xbox network - let it check network. press check again if it fails.
You should have Open/moderate NAT and server connected.
If it fails after more "check again", use the links for advice

It seems that you have blocked IPv6 on your computer.
That is why MWII sub sevices are failing.

My ISP does not provide IPV6 service from what I can tell and never did, so this doesn't seem to be the cause of my problems.

Today after trying a couple times a day and changing nothing, even after trying a completely different router, the game launched into the menu and seems to be working just fine now. I have yet to actually join a match, but there seems to be no issue.
