I recently converted my FreePBX from a HTTP to HTTPS instance. On the same instance, I have Flash Operator Panel2 running on there. Prior to the change, FOP2 login screen or the /fop2 user console would popup rather quickly. After HTTPS was added, I’ve noticed that the login screen doesn’t popup for a little bit.
