I tried to run a solution through Visual studio on my local machine. I get the webpage to appear and receive the error on the page: Unable to connect to the remote server No con
I know this is old but I would like to share what did to resolve this problem. I found out that the cause of this is from the Internet Explorer's Proxy connection is enabled.
You can go to IE > Settings > Internet Options
Then Internet Options dialog will open.
Go to Connections tab and look for LAN settings.
From there, if you see the "Use a proxy server for your LAN (These settings will not apply to dial-up or VPN connections)." checked, uncheck it and press OK.
then that error will be removed.
I hope this helps on other readers experiencing this kind of issue.
