Massive connectivity bug on PC

Me and Friend 1 try to join eachother, stuck on receiving data and we just get a connectivity error. Friend 2 hosts the game, friend 1 join, I join, stuck on ship screen till friend 1 gets kicked from game (not by friend 2) then I join. We have tried, joining eachother while in game, messing with anti-virus and services, restarting our pcs and brute forcing it. Somedays it will work and we can all play. Does anyone have a solution? (Fix this amazing game I want to play.)
