What is the isssue you’re encountering

Hi guys, we are experience the folloqing problem. Let’s start to say that we are working togethere with other partners: 1) The agency (third-party) that hosts the web application (numberone-booking.com) on WIX web servers; 2) Us. We are the agency that has access to the main domain (radionumberone.it) for which we activated the subdomain booking.radionumberone.it. W ejust need to point the subdomain to the WIX web application. We just did it through Cloudflare, but most browsers keep showing ERROR 525 SSL HANDSHAKE FAILED. Our collaborators told that it could need much more time to complete the DNS propagation (we inserted the record A with target IP yesterday in the morning), but also told that it should be necessary to recheck the SSL certificate on domanin numberone-booking.com (web server origin). What do you think about? Did you experienced that?

What steps have you taken to resolve the issue?

We first inserted the record CNAME, but as we didn’t see any change (the subdomain ‘booking.radionumberone.it’ did not redirect to ‘numberone-booking.com’, we switched for record A to target the right IP addresses, and the redirect worked immediately on some web browsers (i.e. Firefox and Safari), but on Chrome and Opera it keeps showing the 525 ERROR SSL HANDSHAKE FAILED.

What are the steps to reproduce the issue?

Just digit ‘booking.radionumberone.it’ into most web browsers.

I believe Wix does not work with Cloudflare’s proxy activated, so you’d need to switch the DNS record to DNS-Only.
