title: Failed to connect to dev.azure.com port 443: Timed out error: Could not fetch origin
body: <p>I have a huge problem connecting to a repository in Azure DevOps. When changing a branch in the local repository or trying to refresh, the following errors occur</p>
  <pre><code>PS H:\damian\Azure DevOps\xxx&gt; git remote update origin --my_branch
  Fetching origin
  fatal: unable to access 'https://dev.azure.com/xxx/': 
  Failed to connect to dev.azure.com port 44: Timed out
  error: Could not fetch origin
  </code></pre>
  <p>After clearing the credential manager, new errors appear when trying to switch to another branch</p>
  <pre><code>&gt; git checkout -q xxx
  error: cannot stat 'Generic_initializaton/Libraries_and_Settings.sas': Function not implemented
  error: cannot stat 'Generic_framework_macros/ABT_structure_verification.sas': Function not implemented
  </code></pre>
  <p>Generally the whole list of scripts is generated - as if GIT doesn't see it</p>
  <p>Please help, I've never seen this before and I'm running out of ideas</p>
