Unable to open site

I was ordering on Walmart and was kicked out.  Have not been able to reconnect on any device we own.  This is the error message - The connection to www.walmart.com was interrupted while the page was loading.

    The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
    Please contact the website owners to inform them of this problem.

www.walmart.com didn’t send any data.       This was on Chrome

I have been using the site for years and don't know what happened.  Tried ipad, desktop, laptop, tablet and nothing connects.
