Hi there,
I can see that the latest post, https://www.samarcanda.biz/colorado-e-utah-la-terra-dei-navajo/, was send to your subscribers correctly. Could tell them to check on their spam folder for the emails.
I can see an error with the connection between your site and Jetpack, that could affect the Newsletter functionality. I am getting the following connection timeout error:
http_request_failed: cURL error 28: Operation timed out after 5002 milliseconds with 0 bytes received
Jetpack, the WordPress mobile apps, and some other plugins and services use?xmlrpc.php?to communicate with your site. This error means your site’s?xmlrpc.php?file or the site itself is taking too long to load. It could also mean that your host or a security plugin is blocking our connection attempts. Another possibility is that your host’s DNS servers cannot resolve requests in a timely manner, and the cURL request times out. This is likely something only your host can help solve.
- To fix this issue, please do the following: alllowlist Jetpack’s IP ranges:?If your host or a security plugin you’ve installed is blocking access to?XML-RPC, please?allow access to our IP addresses, as described on this page:?https://jetpack.com/support/how-to-allowlist-jetpack-ip/
- Contact your hosting provider/developer about making your site more efficient. Your site is loading pretty slowly at the moment. The site performance tool GTMetrix returns a timeout error, indicating that your site is not working correctly. I recommend addressing this issue, as your visitors will benefit from a faster site.
Let us know how it goes.
