Unable to connect to messaging server.

Unable to connect to messaging server.

Folks,

I am seeing the error message of "Unable to connect to messaging server." when I am using Zoho mail in my web browser. (Safari/Mac OS X).  Access to the same account from my phone seems to work normally.  I've tried restarting my computer.

The page itself will load normally, and I can refresh my page, and that will show new messages.  In looking at the JavaScript debug window, it appears that it is calls to:

https://wms.zoho.com/register

Which are timing out after the page initially loads.
