Adsense Plugin issue – Site Down or Unavailable

HI,

Attempting to set up Google Site Kit to run Google Adsense. Site Kit seems to setup correctly & says it will put code on each page, to run Adsense.

Search console seems to setup but Adsense returns this message:

_______________________________________________________________________________

“We’ve found policy violations on https://jauntylife.com that are preventing your site from being approved:

Site down or unavailable

We found that your site was down or unavailable. We suggest that you check your application to see if there was a typo in the URL you submitted. When your site is operational, you can resubmit your application. We’ll be happy to take another look at your application.”

The referenced site above isn’t down and I’m not sure where to go with this.

Google support forum suggested that:
1. perhaps Adsense code wasn’t added to the site, but I’m not sure how to confirm this.
2. using a different plugin to add adsense?
3. adding the Adsense script manually. Not really sure how to do that ether.
4. Site security is too tight? – We’ve backed down some of our security since.

Any suggestions to get Adsense up and running would be greatly appreciated!

Thanks
