Summary

When cloning/pulling via SSH from a mirror, all requests for LFS files get redirected to the Upstream rather than simply converting to an HTTP(s) URL of the Mirror itself. HTTP(s) on the other hand is not affected and successfully retrieves all content from the mirror without the need to contact the upstream.

Steps to Reproduce

Add a Mirror to your DC instance and sync a repo with LFS files. Attempt to clone the full repo from the mirror with "CURL_VERBOSE=1" and you will see the connection to the upstream

Expected Results

All content, LFS included, should be downloaded from the mirror.

Actual Results

Regular Git content is retrieved from the Mirror but once complete, LFS files are then retrieved from upstream.

Workaround

There is no workaround for SSH but you can use HTTP instead to retrieve all files from the Mirror.
