UPDATE 04/12 [image] KNOWN ISSUE: Backend Error After No Man's Land Update Technical Support Hi all, we’ve made some changes on our end and we’re keen to hear whether you’ve noticed any improvement? UPDATE 05/12 [image] KNOWN ISSUE: Backend Error After No Man's Land Update Technical Support To those still experiencing errors; could you check if you have something called cFosSpeed installed on your PC? This software is often pre-installed on systems with MSI or Gigabyte motherboards, but it is not required for Windows or normal network operation. We’ve recently identified that this application is causing Error Code: 2011 and Error Code: 2020, and we’re now wondering if it could be contributing to Backend Error also. cFosSpeed has also been known to cause packet loss and high late… UPDATE 27/01 [image] KNOWN ISSUE: Backend Error After No Man's Land Update Technical Support We’ve made some improvements in 1.10.4, let us know how this impacts your experience crossed_fingers

So I’m on ps5 and I’m at a point now where the game is just about unplayable from the lag I receive. I never had this issue before and has been ongoing for at least a week now.

I’ve been waiting for over and month for any kind of fix and all. I’ve gotten nothing. Either fix this or give me my money back.

Devs really stopped caring. No attempt to address what is going on. No answers. No commitment to fixing it. They are happy with letting a percentage of the population just stop playing their game. Absolutely disappointing.

It’s still not working, still impossible to play, please do something! What’s the problem? Are our IPs banned from your servers? The game worked perfectly fine from the start, why is it impossible to connect to a game we purchased? console-2026-01-14-19.16.16-d38970a4-a4bf-4d8e-bbd2-385bf2b632f0.log (25.2 KB) console-2026-01-02-17.50.57-20fb0d35-1aae-4445-af95-8dbbca31ccb1.log (21.3 KB) console-2026-01-03-09.40.54-e4b8f3dc-9cab-48a5-bef2-ad0a828a9e15.log (21.7 KB) console-2026-01-04-10.40.35-d658c8f4-f90c-4f59-922f-3c4ad355773e.log (21.3 KB)

We’ve made some improvements in 1.10.4, let us know how this impacts your experience :crossed_fingers: [image]Patch 1.10.4 - Patch Notes This patch comes with several technical improvements that we hope will increase stability and network performance in the game. It should also improve playing on slower and/or unstable network connections.

Still getting same backend error.

@d3sp4ir out of interest, what’s your connection type? Is it a normal home connection, or a semi-public one (like on a university campus, military base, etc.)?

I’m still getting the same error. Haven’t been able to play for months now

It’s a home connection. Edit: I’d like to add that the last time I tried 4 days ago, I quit out of frustration upon seeing the “response to Fatshark server is slow” message. I tried it again today and still got the same message but decided to wait and managed to load in. That potentially means that whatver fix was deployed latest seems to have worked (for now..) I’ve attached the console log below. console-2026-01-31-08.09.58-a72cacbe-6b56-4cca-b51c-5f25dca69279.log (89.0 KB)

I’m still having this same problem after trying all these “fixes” and still haven’t received a reply to my original post. At what point can I ask to get reimbursed for a game I can’t play?
