Mario Kart 8 Lan play on single PC, not working in development builds (5.0-6803)

I have 2 instances of dolphin lanned together working fine on 5.0 stable

on the last few development releases I've tried, there are two variations of the problem when attempting to connect in lan mode

1) sometimes one gamecube finds the other, and not vice versa. Pressing 'a' on the gamecube that detected the other will cause the respective dolphin instance to cease up
2) both gamecubes find each other, pressing 'a' on either instance will cause both dolphin instances to cease up

Screenshot of one gamecube finding the other, but not vice-versa (never see this issue in 5.0-stable)

You need the use the newest versions of openVPN and whatnot. I had the same issue when checking the PR.

Thank you for the assistance, I just tried doing a clean uninstall, then install of the latest version of openVPN. However, I still have the same issue in the development build, and it is still working perfectly in stable.

Can you bisect to the build that caused it to stop working for you? Potentially something other than the issue I'm referring to has caused a regression then.

Sure, let me try some older builds and get back to you

So I guess it is working in the latest development builds under default settings.

It strangely seems to be some sort of setting that is messing it up. 6880 is working with everything set to default, when I change to vulkan, make a few graphics adjustments, make a few audio adjustments, enable cheats etc. something messes it up. I'll try to pin down exactly what is causing it

Alright! Thanks for the update. I was worried that maybe it was some different in our PCs, since it was working for me.
