I have the same problem !
PlatformCook: Error: We hit an error while cooking this content
PlatformCook: Error: errors.com.epicgames.content-service.cook_failure
PlatformCook: Error: CookJobId:c495f504-dbed-4334-8659-f114f101937c
PlatformCook: Error: An error occurred while communicating with the game servers (failed to cook module 46779e46-4e14-df0a-383d-c08fee00dbab (artifact ca12f122-126f-48ea-b355-df03506b5a3e:linux-server) (cookJobId c495f504-dbed-4334-8659-f114f101937c) with error code errors.com.epicgames.cookplugin.cookfailure).
So I have to deactivate the streaming option? but it’s weird because I activated it at the beginning of my map (2 weeks) I would have had the error before, I think, and if I deactivate it and reactivate it afterwards it could work?
