Data Center 2002 Error (LAN)

Hello!

I have a curious issue when I try to play my game with LAN connection:

I can get to the Start menu with LAN but I always get the 2002 error, my internet didn't update or anything and I've been playing wired from a long time, however if I switch my connection to WiFi I can play normally (except I get lag spikes which is why I play LAN over WiFi)

I tried to do the Internet Explorer steps specified on other threads but it didn't work.

Hope I explained it well, in short words I can play with Wifi but I can't in LAN, and I need LAN since lag spikes doesn't let me play properly.

Thank you very much!

Check your windows network settings, if it is set to public network then change it to home or trusted network. Also check your router settings, make sure your LAN network is not blocking anything.

Hello!, thank you for replying

I changed my network to thrusted and I've been checking my router configuration but I found nothing plus I don't really know what to look for, I already checked most of configurations, also, no one can change my router config so I don't think that's the problem.
I'll keep searching about it, maybe auto updates or smth on my router.

Hi!
No changes have been made on my network, I've been experiencing this since August 22nd, I played wired with no problems before that date, even the day before I was playing flawlessly

Hello!

I've got good news, looks like it was Killer Network Service, I stopped the service and I was able to log wired again, I tried looking for a setting in the Killer Network app but I found nothing right now, I hope this works to anyone with the same problem in the future.

Thank you very much for your help!
