WE CONTINUE TO HAVE THIS PROBLEM!!

WE CONTINUE TO HAVE THIS PROBLEM!!

myself and co-workers continue to get this connection error.  We are able to navigate to other websites, but once this appears we must log off and power down the computer and restart in order to access Zoho Mail.  (and sometimes even that is not successful)
We have tried clearing all the cache and history & We have tried NOT clearing the cache and history. 

Once we get this error, it appears again on any google search we do.  we can switch to bing or yahoo and it will return search results - NO BROWSER WILL ALLOW YOU TO ACCESS ZOHO MAIL until you power down and re-start.

I am able to navigate to ZOHO CRM and access my email, but some employees do not use CRM and are fed up with this issue.

We have called or reported the problem and it seems to "go away" for a while but inevitably IT RETURNS!  It has become such a frequent problem with our team, I am considering dumping ZOHO!!

ZOHO is our email host and this problem occurs on ALL browsers.

PLEASE HELP!!
