"Unable To Connect" - Web Interface

[TrevinM]

Lately whenever i try to connect to my Plesk Panel, I get Firefox's "Unable to connect" error and with Internet Explorer I get "Cannot display web page". I disabled all addons, still couldn't connect. Checked my Firewall, still nothing. I pinged the IP and got 51ms. My site is still up. And I just dont know what's wrong.

If anyone knows what's wrong please reply.

Have you tried connect to https://ip_address:8443 ?
Are you sure that Plesk service is started and port 8443 is not firewalled?
Additionally use article http://kb.parallels.com/en/111289 for troubleshooting.

Can you check if plesk control panel site is correctly configured in IIS. Or let us know your server RDP details and we will get it resolved for you.
