Hi
We have a domain that originally validated successfully when uploading the .well-known/apple-developer-merchantid-domain-association.txt and I am currently successfully transacting Apple Pay payments.
Now we need to renew/verify again as the validation expires on the 10/01/2019 and I get the following error…
Verification failed for domain - Unable to establish a secure connection to 'https://{mydomain}/.well-known/apple-developer-merchantid-domain-association.txt'. Domain certificate is untrusted.
If I browse the .well-known URL all appears fine.
I have used Qualys SSL Labs https://www.ssllabs.com/ssltest/ who have rated the SSL A with Extended Validation.
The only difference I can see from when we previously verified and now is that we have a new SSL and the insecure TLS 1.0 is now disabled.
The issuer of the certificate is “COMODO RSA Extended Validation Secure Server CA”
Any help would be really appreciated.
Kind Regards
Luke
