RMC accomplishes downloading of HTTPS content, such as at https://www.youtube.com, by creating a proxy. When monitoring for internet downloads is turned on, the proxy setting is activated. If RMC is unexpectedly shutdown, the proxy setting might get left on and interfere with internet communications at the next boot cycle. You can go to Control Panel\Network and Internet\Internet Options, select the Connections tab, and click the "LAN settings" button to turn off the proxy setting. This should re-enable the internet connection.
