I'm sorry for the confusion, but the problem is not within the git command itself. This works fine. But we use the distributed curl command for POSTing data in a custom script when we deploy to production. So the problem is with how the curl command is built for windows. It used to be built with HTTP/2 support, now it is not.

The reason is that the default SSL/TLS backend is Secure Channel, whereas Git can be configured to use OpenSSL instead. And looking at the most recent build of Git for Windows' cURL, I see in https://github.com/git-for-windows/git-for-windows-automation/actions/runs/14221753030/job/39851304688#step:16:1230 that the OpenSSL version is compiled with HTTP/2 support whereas https://github.com/git-for-windows/git-for-windows-automation/actions/runs/14221753030/job/39851304688#step:16:2854 shows that the Secure Channel version is compiled without HTTP/2 support. When you configure `http.sslBackend = openssl`, does it work then? Ciao, Johannes P.S.: The bug reporting template of `git bugreport` sadly omits useful hints such as including the contents of `/etc/install-options.txt`, where others could easily see whether you chose the Secure Channel or the OpenSSL backend as Git's default. > > What's different between what you expected and what actually happened? > I expected curl to be able to run as before when contacting our backend in our maintenance scripts. I'm not allowed to install a custom curl on our corporate network, and the windows version does not support HTTP/2 either.
