Strange dissconection

I load up a game. everything is normal. everyone gets to 100% loaded. Normal this takes about 30s to 60s to finally load in. but it takes multiple minutes, for me to just crash. I reconnect, and the typical "you cannot connect" thing pops up. after I finally give up trying to load in and click cancel, the game has remade, and I am now in low priority que. this has never happened before in such a fashion, and I would like an explanation or recompense. This is different because whenever this happens, not only is there usually an obvious reason, but everyone never loads past 0%.it is also worth noting that this is not associated to lag on my part.
