We’re investigating this here: [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)

Closing this thread so another ticket isn’t created.
