error message is blocking access to crm

I get the following message when I try to use the CRM data that I have imported.

The connection has timed out

The server at salesiq.zohopublic.com is taking too long to respond.

    The site could be temporarily unavailable or too busy. Try again in a few moments.
    If you are unable to load any pages, check your computer's network connection.
    If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.

Why is this happening?
