I can confirm the issue is resolved now. Apple has fixed domain verification on their side.

It's the same way we submitted the request 101417655497. OK, another attempt. New ticket number is 101442396173. Here is a confirmation: """You will receive an email shortly with a follow-up number from Apple Developer Technical Support""". And email: """Thank you for contacting us. We’ve received your support request and will get back to you in one to two business days. Your case number is 101442396173. For additional information on development-related topics, visit Apple Developer Support. Best regards, Apple Developer Program Support.""" Also none of these two tickets are visible inside our account profile. Should they?

Yes we're still stuck with the issue. Could you please provide a link or guide how to submit a proper TS ticket? Regards

Dear Matt. We're still waiting for any reaction on the Technical Support ticket from Jun 22. BTW its ID is 101417655497. Thanks

Here is a TSI case ID: 101414548327

Hi Matt. We have an incident open for over a week, its number is 770249757. We've sent an update to the incident asking to assign you. Thank you. Opps, I've just found it's a Merchant Support not a Technical Support. I'll open a TSI

You say "Prefer Elliptic Curve". But all cipher suites you listed are RSA ones. We're experiencing the same TLS issue now. Our website uses ECDSA certificate and every ECDSA suite listed in the "Setting Up Your Server" article works fine. However domain verification fails and our server log says "none of the cipher suites supported by the client application are supported by the server". Please advise
