I have seen many users post this question only to find the solution was to increase the buffer size.
I pushed one small Unity project (~50M) just fine after following this advice. I had to increase the buffer size to 1M, but I was successful.
My second Unity project (~75M) isn't much bigger, but I got this same error even when I increased the buffer size all the way to a seemingly absurd 512M.
Does anyone have any suggestions? I know this error gets reported a lot so please mark this as a duplicate if there's a legitimate answer.
