Connection problem solved

 Received this notice from a website I use daily.  
At first thought it was a website problem. 
Only had this notice on one of two computers.
Ran a virus program, no help.  Internet searches did not help much either.
Then I decided to save my bookmarks and other pertinent browser details. Uninstalled Chrome completely and reinstalled Chrome.  Problem solved.  Appears an undetectable addon may have been in the browser.  Have to uninstall and reinstall other browsers on that computer
