• Prolonged Load Time:​ The Backoffice takes one minute or longer to load completely after login.
• Proxy Error Message:​ Sometimes, the following error message is displayed:
  

  Proxy Error - The proxy server received an invalid response from an upstream server. The proxy server could not handle the request. Reason: Error reading from the remote server.
