Git push hangs in macOS

[Marco Burato]

Last Friday, when I tried to push my changes to Bitbucket from SourceTree, it would hang after

POST git-receive-pack (144321 bytes)

I assumed it was a temporary server issue.

Today I tried again, several times, and it always hangs.

Then, I tried to push something from SourceTree on Windows and that worked. So, this seems to be a problem specific to macOS.

I have tried the following, without success:

• Rebasing changes
• Pushing smaller changes
• Logging out and logging in again in SourceTree
• Switching SourceTree from Embedded GIT to System GIT
• Pushing from CLI

After enabling CLI tracing with

GIT_CURL_VERBOSE=1 GIT_TRACE=1 git push -v

it looks like it's hanging waiting for a response from the server:

So, this appears to be a server issue, possibly when using a macOS client.

Please advise.

I was able to overcome this by forcing the use of HTTP 1.1:

git config --global http.version HTTP/1.1

Looks like there's some compatibility issue between the client and the server with HTTP 2.
