Does anyone else have this problem? Every single game I join, I get disconnected after a few mins with a "lost connection to host" message. I can't find any fixes online.

The only other thing I can think of might be FPS related. I had a similar issue in COD 4 and the only thing that resolved it was capping the FPS.

Hey DAR,

Thanks for getting back to us.

Does your PC have Wi-Fi capabilities at all?
If so, can you please try using a mobile hotspot to see if the error still occurs on another connection?

Firstly, disconnect the mobile from any wi-fi connection, then turn on the hotspot feature.
Then connect the PC to the hotspot and try to load into a game.

If not or that doesn't help, please also go through the following two connection related articles and try any steps that you have yet to do.

Article 2[team17.helpshift.com]

Get back to us when you can!

Any luck resolving this? My buddy is having issues with it and it sounds like the same problem.

I haven’t had a chance to try the hotspot test yet. No luck so far. I’ll give an update.

Having the same issue from the U.S. Every game I get a disconnect. Unplayable.

Hey ushmel,

Thanks for getting in touch - sorry to see that you've experienced a similar issue.

Can you please confirm if your friend has tried all the steps listed above?

We would also recommend they try a hotspot if possible as this may help us establish where the issue is coming from.

Please do let us know and we can investigate further.

GulfcoastKilla1 - we have replied on the thread you have created regarding this and will continue support over there :)

I'm unable to connect to a hot spot. The two links don't apply since the error messages they address are not the same as the error message I get. I get a message stating "lost connection to host".

I know this is a game issue and not a PC or user issue because the game ran fine for me when I played a lot a few months ago (around the initial British update). I started playing again this month and now I'm getting DC'd from literally every game after about 10 mins. Please fix your game.

Hey DAR,

Thanks for your reply - that's no worries at all.

The two articles listed above, while different error messages, have also solved the Lost Connection to Host error for other players so we would recommend running through those steps also and if the issue persists, we can investigate further!

Get back to us when you can.

I have a potential fix. Try plugging your PC directly into your modem. Ignore your router entirely. When I did this the problem stopped, which narrowed the issue down to my router. The game has some sort of issue with how it was communicating with the stock firmware on my netgear router. I don't know if this applies specifically to netgear hardware or if this is a more general issue. In the end I installed open source firmware (openwrt) to replace the factory router software and it solved the issue immediately. I know this fixed the problem for at least one other person who also had a netgear router.

This is an extremely frustrating issue. I highly doubt Team17 is doing any testing to address the problem since this bug has been reported over and over again since around the time of the British update, which was when my game started doing this. I wasn't able to play the game for over two months until I got to the bottom of it myself.

Is there any update on a fix? It seems like a lot of people are having this issue.

Hi both,

Thanks for getting back in touch with us.

As mentioned above by lawn boy, the issue is quite often related to or caused by a player's router or ISP. Many players have resolved this issue in the past with a different/new router or some reported changing ISP should that be something you wished to do.

We're unable to troubleshoot player's connections due to the many different connection set-ups and ISP's available, if the router has firmware causing the error to occur, this is not something that the game can resolve.

We do recommend to go through all of our connection based help articles on our support site[team17.helpshift.com] as the steps provided have all helped player's with connection issues in the past and these are built from our player fixes and recommendations.

We would also highly recommend to also reach out to your ISP to check for any firewall or firmware on the router, try using a mobile hotspot disconnected from the Wi-Fi if this is possible (if this works then this confirms an issue with the ISP connection), or changing router where also possible.
