Why does git push fail?; "error: RPC failed; curl 18 transfer closed with outstanding read data remaining"; "send-pack: unexpected disconnect whil

Question

I have been trying to git push some files into a repo I just created, but it keeps failing.

I've already tried changing http.version from HTTP/2 to HTTP/1.1 (I've tried both) and I also increased the http.postBuffer and http.maxRequestBuffer size. Most fixes I found online recommend changing one or both of these.

The largest file in my local working directory is 24.6 MB (excluding a .pack file) so I don't have to use Git LFS.

Here is some of the output of git config --list:

diff.astextplain.textconv=astextplain
filter.lfs.clean=git-lfs clean -- %f
filter.lfs.smudge=git-lfs smudge -- %f
filter.lfs.process=git-lfs filter-process

branch.main.merge=refs/heads/main

And here is the output after git push:

Total 177 (delta 5), reused 177 (delta 5), pack-reused 0
fatal: the remote end hung up unexpectedly
Everything up-to-date

I am using no antivirus/firewall other than Windows Defender.

Please help.

In my situation, I was trying to push too large a payload. According to this article, "Because github does not allow a single push larger than 2GB you can push it in batches. Split the push into part1, part2…"

My solution was to break up the payload into several commits and push a couple at a time. Depending on your situation, you could try writing a shell script to push incrementally up to HEAD if you have commit history on your repo. I didn't end up doing that but instead, I made ample use of matching patterns with multiline git add commands to select the files I wanted for each push.
