You memberships appears to have expired? Support does require a current subscription. Nevertheless...
This is because google is not "seeing" your site as end user would - if you look at the image of the site they show you you will see it doesn't look right - this is because googlebot has been prevented from accessing certain directories because of the content in your robots.txt file in your joomla root directory. You will need to comment out the lines that currently specify "disallow" on cache,components,libraries,modules and plugins (add a # at the start of the line). You could also make this change specifically for the googlebots too.
This is what I use:
User-agent: *
Disallow: /administrator/
Disallow: /bin/
#Disallow: /cache/
Disallow: /cli/
#Disallow: /components/
Disallow: /includes/
Disallow: /installation/
Disallow: /language/
Disallow: /layouts/
#Disallow: /libraries/
Disallow: /logs/
#Disallow: /modules/
#Disallow: /plugins/
#Disallow: /templates/
Disallow: /tmp/
