After installing System Center rollups (in my case UR6) I lost connection between Azure pack and SPF, getting „No Virtual Machine Cloud provider was found“ error in Azure pack management portal.
First, I tested my SPF site
which was not responding. When I logged in to my SPF server, all services were running, so I opened IIS manager and found that SPF website was stopped.
When I opened Bindings, I found two Site Bindings to port 8090, so I removed one and made sure that proper certificate is selected. Then I started IIS website and went back to Azure Pack Management portal to confirm that connection with SPF is working fine.
