Create a sub-domain on wix and connect or route an external domain hosted on godaddy??? SSL error

Dear Wizards,
I have a website/domain on wix, called https://www.example.com I would like to create a subdomain called https://www.beta.example.com on wix and connect a web application hosted in aws ec2 server and using a godaddy domain https://www.example2.com. Hence, when someone opens https://www.beta.example.com they see https://www.example2.com.

I followed instructions and added the cname from godaddy to wix domain DNS manager, which made the above possible. My problem is that I'm receiving an SSL error/invalid certificate, even though both sites have valid SSL certificates and do not show this issue when visiting the sites directly. The http site routing has no errors. Any ideas on how I solve the SSL on the wix-subdomain connecting to an external domain??

Hi,

It would be best to contact Wix support at support@wix.com on this matter.

Let me know if you need any further help.
