title: SSRS Service unavailable HTTP 503
body: <p>This Wednesday our report server stopped working.
  When I open the URL <a href="http://ourdomain/ReportServer" rel="nofollow noreferrer">http://ourdomain/ReportServer</a> as set in <code>Report Server Configuration Manager</code>,</p>
  
  <p>it writes <code>HTTP Error 503. The service is unavailable.</code></p>
  
  <p>I already tried to restart the service <code>SQL Server Reporting Services</code>.</p>
  
  <p>I also tried in <code>Report Server Configuration Manager</code> under <code>Web Service URL</code> tab to rename the Virtual Directory to ReportServer2 than apply. The new URL wasn't working as well.</p>
  
  <p>I noticed in one log from 12. 2. 2020
