git push 错误 - 致命：远程端意外挂断错误：RPC 失败； HTTP 401 curl 22 请求的 URL 返回错误：401

Question

This has completely stumped me. It only occurs when trying to push individual files > 1MB

IC# program that is running on a remote server. The program creates a process and runs a .bat file in cmd.exe.

The .bat file contains basic git commands, it simply checks out a branch, adds files, commits, then pushes

git checkout QA

git config --global --unset http.postBuffer (added for troubleshooting, doesnt fix issue..)

git config --global http.postBuffer 157286400 (added for troubleshooting, doesnt fix issue..)

git add config .txt

git add *.sql

git add *.out

git commit -a -m "Resolve Poll"

git push

I am using Azure Devops to run this program as a build on the remote server and when it goes to do the git push it returns

fatal: the remote end hung up unexpectedly fatal: the remote end hung up unexpectedly error: RPC failed; HTTP 401 curl 22 the requested URL returned error: 401

but when i log into the server myself and run the .bat file by double clicking all the git commands run to success without error, even for pushing files > 1MB

What could this be?

Things i've tried

Updated GIT for version 2.25

Increased http.postBuffer size

git pushed with username pass in url

used both 'store' and 'manager' methods of git config --global credential.helper

Answer 1

The HTTP 401 error (Unauthorized) means you're missing credentials or the credentials you're using aren't valid. You'll need to figure out what credentials are needed and provide them, usually with a credential helper.

It may be the case that when you log into the server, your credentials are delegated (say, if you're using Kerberos or NTLM), whereas those credentials are not present when the server is running noninteractively. You could consider issuing an access token or OAuth token of some sort to the server if you can't use anything else.
