[CRASH} crash during loading screen

so i play on a mac it normally takes me 2mins to load in to a match. but my 1st game of the day today in the loading screen, my game crashed twice saying disconnected from internet but i checked and my laptop was still connected. so i hit the reconnect button and no luck. so i relaunch the game and it takes me an other 2 trys to reconnect will in loading screen. once i was around 80% load it would crash. i didn't load in till about 15mins later.
