Hello @chuimn ,
Thanks for sharing Site Health information.
We’ll test Site Kit with PHP 8.0 version & get back to you.
In the meantime can you please ensure that your site is able to communicate with https://sitekit.withgoogle.com?
There are instructions on how to check with the link provided, or you can ask your host to run the below cURL command to ensure you can access the Site Kit service:
curl -I https://sitekit.withgoogle.com
Note that there may be changes required at host level based on your cURL error, something which is outside of our control. You’ll find a similar support topic previously whereby a user had to change their PEM file.
Best Regards,
