Hi @Flak , ist`s all the same problem and you see that many creators have this issue…

I think you want to bundle all those issues in [Players can't join my map in public, Matchmaking error (errors.com.epicgames.common.processing)](https://forums.unrealengine.com/t/players-cant-join-my-map-in-public-matchmaking-error-errors-com-epicgames-common-processing/2725814)

(but I think it`s not a suitable topic for that problem!)
