Hey, all. I appreciate the connection tests provided so far. I couldn’t find anything shared with the data that we were seeing before. I’ve sent the information to be reviewed to see if one of our teams can look into this further. I’m going to go ahead and remove the initial post requesting connection information.
I want to see if troubleshooting may help some of the disconnection problems, or even provide a workaround for some of you.
-
If you are wireless, please try a wired connection. For those who can’t try a wired connection, is dualband available? You should have 2.4Ghz and 5Ghz wireless networks if you do have a network card and router that supports these frequencies.
-
Try resetting the network devices, then try flushing the DNS.
For Windows 10, try this additional step.
- Click on the Start Menu
- Select on the Settings
option.
- In the Windows Settings, click on “Network & Internet”
- Near the bottom of the new window, click on “Network Reset”
This will restart the system in 5 minutes.
-
Try closing down background applications.
-
Try another DNS service like Google or Cloudflare.
-
If you are able to try an alternative connection or a VPN (if it’s allowed in your country, please check with local laws), do you continue to experience issues?
This isn’t guaranteed to resolve or workaround the problem, but please feel free to share if any of this works or doesn’t work for you. I hope one of these options does work for you.
This is frustrating to run into, and I really do appreciate you working with us and reporting this to us.

Same issue. Started last Friday for me as well. Been on PC less than two months and have already deleted the game twice in the hopes that it would resolve issues. Didn’t work. Done a reset on my PC. Didn’t work. Not to mention all the other generic “troubleshooting” options. Pretty frustrating…

I always am wire connected I was testing it earlier before I saw your response and i didn’t get the error but I didn’t test it for long as well as I restarted my router and disconnected everything and let it sit while I had dinner. I also scanned and repaired the files as well while my internet was disconnected due to people being on the internet at the moment, I stopped my test and will resume troubleshooting/testing to see if what I have done has fixed anything later when everyone is asleep and I have the internet to myself to see if my latency is normal like it usually is around the time when I have the internet basically to myself and will report my further findings to this forum.

Yes, I am heaving this problem and the battle.net going offline too. if I change the region to “asia” the error does not happen. I’m from Brazil, Mato Grosso, Cuiabá.

I have been having the same problem- get dissconnected after maybe 20-30 minutes of playing war zone. This all started with the battle net update from last week. After reading all of these replies it seems the problem is with the update. I hope blizzard is looking at it or even thinking about going back to the previous version of battlenet.

Yep, if you watch the battle. net client you’ll see it briefly disconnect and then reconnect. Long enough to kick you out of the game. Even if the game is not running if you watch the Battle . net client for long enough you’ll see it happen in the top right.

I’ve put in a support ticket. I’m worried this is just going to get looked over cause BOCW is coming out and they’re already going to have a load of issues with that on launch and leading up to. I’m on the fence (was excited) about previously preordering BOCW cause I’m not sure if it’ll even work given this seems to be a battle. net client issue.

My thoughts exactly. Really didn’t have any major issues prior to last Friday. Has to be related to the update…

Any news? Its been almost an entire week and I still can’t play without Battlenet disconnecting.
EDIT: I tried clicking on the world icon on battle net next to Warzone and switching to Asia. I was able to play for an hour with 50 ping even tho I live in Europe… That tells a lot about whats wrong…

Earlier in the thread someone mentioned setting your region to Asia. Thought I would give it a shot. So far I’ve made it over an hour without a disconnect. Easily the longest I’ve made it so fingers crossed. I live in the United States so it seems like a dumb fix, but a potential fix nonetheless. Good Luck.

I tried that but after trying that my ping was outrageous and unplayable
Just send out a Roll Back Client update.
Still got the problem, flushing DNS or play with you connection doesn’t fix anything, it’s not coming from your side… The only thing true is that it came with the last update for sure.

"Greetings Jacob,
Tech Specialist Ektiledil at your service. I’m afraid Blizzard Support can only assist with payment and installation issues when it comes to Call of Duty games. With any other issues and queries please contact Activision: https:// support. activision. com/contact_us
As for error BLZBNTBGS000003F8 with Blizzard games we are currently gathering logs witch need to be gathered using LogGoblin ( https: //eu . battle. net/support /en/article/28923 ) and sent to techinfo@ blizzard. com with subject “BDA Constant Disconnection [13063]”. You can gather logs and send them to us but we can’t guarantee a solution as COD:MW is not a Blizzard game.
Regards,
Blizzard Entertainment

Asia servers started to work for me today. Good luck playing with any of your friends though. I tried and it was Lag city, although it was better than not being able to play at all. I’m going to do Solos with some people from Laos I guess lmao.
Multimillion-Dollar company and they still don’t know that the client itself is a problem, disconnect for a couple of seconds, and reconnect back. This causes the game to lose connection with Blizzard. If the issue was COD it would have not worked with the other platforms.

Yep, I can play freaking Dead By Daylight an indie studio game but AAA Call of Duty wont work. Its a Disgrace.
I already put my ISP through the ringer the past week thinking it was an issue on their side because Blizzard was so confident it wasn’t an issue with them.
I wouldn’t even trust blizzard to launch Runescape at this point.

OMG it’s worse today!!! I open up MW and I’m disconnected before I can select Warzone or MW Multiplayer. Happening every single time I connect within a minute or less. This is extremely frustrating.

Closing google gave me an extra 30 second to load into a game then I was disconnected…
Tried the flush and loaded up the game. The game froze right away resulting in having to hard shut down my PC and repairing windows…
Why can’t blizzard roll back before whatever horrible update they pushed last week. I had no issues before that update to the app.
