Good morning.
I recently purchased two SSL certificates. When checking the certificates, the following information appears: The hostname 3cantos.me is not listed in the certificate. SERVER: Common Name: joaquinis.synology.me
SANs: *.joaquinis.synology.me, joaquinis.synology.me
Validity: From 10/11/2025 8:49:24 PM to 1/9/2026 8:49:23 PM
Serial Number: 54d9199b025a06aa0270c44a19089da8324
Signature Algorithm: SHA-384withECDSA
Issuer: E8.
I have Synology Mail Plus configured on a Synology NAS with DYNU. The domain name of my Synology NAS is: joaquinis.synology.me.
The same thing is happening to me with the other certificate I purchased for mail-plus.net.
How can this be resolved?

Thank you very much for your attention.
Sincerely,
Joaquín
