Sourcetree 3.2.6 FATAL ERROR: Server unexpectedly closed network connection


Whenever I try and clone anything through Sourcetree 3.2.6 it outputs this error, on any computer. However, I can access the repositories through the command line just fine.


"git -c filter.lfs.smudge= -c filter.lfs.required=false -c diff.mnemonicprefix=false -c core.quotepath=false --no-optional-locks clone --branch master D:\Dev\Repos\project
Cloning into 'D:\Dev\Repos\project'...
FATAL ERROR: Server unexpectedly closed network connection
fatal: early EOF
fatal: the remote end hung up unexpectedly
fatal: index-pack failed

Completed with errors, see above."


I have run out of steps to try and fix this, my Google-Fu has failed thus far.

Did you find a fix for this?

Not yet, it seems to be better now a little bit but if you just keep retrying it eventually goes through, it only happens on the first clone.


You can also pull the Repo via command line and then hook it up in SourceTree, I have been doing that for now when it happens.

Yes, git bash command line works.

Through Sourcetree, it seems to throw the error only for our large project. The Sourcetree clone operation works for all other (regular-sized) projects.

I've found that it does work in Sourcetree if you change the clone depth to 1 (under Advanced Options > Clone depth). This is a git "shallow" clone, which lets you pull down just the latest commits, not the entire repo history. A depth of 1 copies only the latest revision of a repo.

I've also read something about changing the git http.postBuffer size, but I haven't explored that. We're using SSH, so I'm not sure if that has any impact.

I will give that a try next time I encounter this problem.

Just to let you guys know, we had the same problem but changing clone depth to 1 did not help. Our repo size is around 300MB.

It turns out the issue is that folder that we clone into did not exist. We had to create on Windows. We also tried

Not sure which one fixed the problem.
