Hello, We are using Let’s Encrypt certificates and everything is set up correctly. I can see in our logs, that apple servers visited our domains, but validation failed. I have contacted apple support and bellow is their answer. So it looks like they need to fix it and we have to wait and hope:) For the automated validation, we have checked with our engineers the automated validation process is failing due to the developer’s SSL certificate chain, this is common for short-term certs issued by providers such as theirs, Let’s Encrypt. Specifically, the your SSL cert chain does not contain the values in the subject of the cert chain for which our automated job checks. Due to the lack of values, our automated process is expected to fail. We are working on for some enhance but in the mean time, we would ask you to make sure that you renew your certifciates manually.

Hi, do you have any news? We have the same issue. Thank you
