title: GIT LFS is stuck in filter-process command
body: <p>I have a GIT repository in Bitbucket, which uses GIT-LFS:</p>
  <p>Whenever I try to clone the repository, <code>git-lfs.exe</code> gets stuck with the following command-line:</p>
  <pre><code>&quot;C:\Program Files\Git\mingw64\bin\git-lfs.exe&quot; filter-process
  </code></pre>
  <p>This happens in all of the following cases:</p>
  <ol>
  <li>When I try to clone the repository directoy (using <code>git clone https://...</code>)</li>
  <li>When I try to add the repository as a submodule (when running <code>git submodule update</code>)</li>
  <li>After I abort any of the above commands and run <code>git reset --hard</code> in the clone of the repository using GIT-LFS (which then has missing files and changes).</li>
  </ol>
  <p>I am using</p>
  <pre><code>$ git-lfs --version
  git-lfs/3.1.2 (GitHub; windows amd64; go 1.17.6)
  $ git --version
  git version 2.35.1.windows.2
  </code></pre>
  <p>and also had the same problem with</p>
  <pre><code>$ git-lfs --version
  git-lfs/2.12.1 (GitHub; windows amd64; go 1.14.10; git 85b28e06)
  
  </code></pre>
  <p>I have several other working directories where the same repository is a submodule, and running <code>git submodule update</code> in these works fine (but there are no changes, so the command doesn't really have to do anything).</p>
  <p><strong>UPDATE: After enabling tracing, as suggested in <a href="https://stackoverflow.com/a/71758833/2279059">this answer</a>, and waiting long enough, it turned out GIT LFS is &quot;stuck&quot; while downloading the actual files from LFS, which just seems to be extremely slow (despite the total size of the files being only about 1 GB. File dates suggest the total download took over 1.5 hours!). It eventually finishes, and all files are where they should be. This maybe an issue related to Bitbucket. Any suggestions on what could cause this (other than contacting Atlassian support)?</strong></p>
  <p>(Any advice on how to debug this issue is also a valid answer)</p>
