Running dnn 7.2 on Azure. Site intermittently goes down and gives error: "There is a problem with the page you are looking for, and it cannot be displayed. When the Web server (while acting as a gateway or proxy) contacted the upstream content server, it received an invalid response from the content server."
I have to login to Azure and restart the sites periodically, then they seem to work for a while. Any idea on where to start troubleshooting in azure? I've looked in the Dnn logs and don't see anything out of the ordinary.
