title: Atlassian Bamboo connecting to SVN over HTTPS
body: <p>I am evaluating Bamboo as a CI system (currently using Team City)</p>
  
  <p>I am falling at the first hurdle, which is trying to get Bamboo to recognise my repo which is over HTTPS at a third party site (standard username &amp; password auth)</p>
  
  <p>The error given is:</p>
  
  <pre><code>This is not a valid Subversion Repository: svn: E175002: Received fatal alert: unexpected_message svn: E175002: OPTIONS request failed
  </code></pre>
  
  <p>TeamCity connects perfectly, running from the same server using the same repo and the same authentication, and I can connect to the repo using HTTPS in the browser</p>
  
  <p>The SVN repo is running 1.6, so I pre-configured that in the Bamboo options (default is 1.7)</p>
