Welcome to the Cloudflare Community :logodrop:

Have you set up the required items referenced in the error message that you provided?

Can you share your domain name so the Community can provide more specific guidance?

Nons.co.il and IP is - 185.28.153.88

Thank you for sharing the domain name.

You have an invalid SPF record due to the recursive reference.

v=spf1 ip4:185.28.153.88 include:nons.co.il +all

By placing include:nons.co.il inside the record located at nons.co.il you have created an infinite loop which renders the record unusable. You need to remove that include mechanism from your record.

I reccomend using the dmarcian SPF Surveyor to examine your record.

This is fine…?

No. You can clearly see the include:nons.co.il part that must be removed is still present. You must delete that from the record or it will not be valid.
