Ads not showing because your website is unavailable

Recently went to check on an ad campaign in google ads because it was not working.  Error at top of google ads says "Your website is unavailable" so add campaign is disabled.

Of course the site is up and running.

So next I went to https://search.google.com/test/rich-results? and entered the domain http://rioslawoffice.com.

Searching on this error, I see multiple posts from squarespace, saying "this is not a problem."  However, I can not run ads because Google DOES think it is a problem.

Can someone point me to a solution?

Thanks.
