LFS > 100 MB fails to push to azure devops

[Herb Train]

Hi, all. I managed to set up a remote azure dev ops repo and push/pull without issue from a couple of windows laptops. I then initialized LFS and was still able to push/pull small tracked LFS files. However, any LFS tracked file type larger than ~100MB fails to push with the following error (partially redacted): 

git -c diff.mnemonicprefix=false -c core.quotepath=false --no-optional-locks push -v Azure_Devops_Remote__-_MYPROJECT master:master
fatal: Cannot determine the organization name for this 'dev.azure.com' remote URL. Ensure the `credential.useHttpPath` configuration value is set, or set the organization name as the user in the remote URL '{org}@dev.azure.com'.

Locking support detected on remote "Azure_Devops_Remote__-_MYPROJECT". Consider enabling it with:
$ git config lfs.MYREMOTEURL/info/lfs.locksverify true

In regards to the error, I'm not sure how to "ensure the 'credential.useHttpPath' configuration value is set' but my org name is already set as the remote user in the remote URL. Also, I'm not sure how to enable locking support through Sourcetree. I also tried adding an account under Tools/Options/Authentication and while it was accepted, it didn't help.

I'd be very appreciative of any suggestions to try. Thanks in advance!

This thread contained the answer for me in case anyone else if having the same problem. TLDR - run the line below:

git config http.version HTTP/1.1

I'm not sure how to do that from within Sourcetree, of course, but it seems to fix the issue.

Still happening.
