Exchange Server 2013 provides secure client-server and server-server network communications by using SSL certificates to secure protocols such as HTTP, SMTP, POP and IMAP.Because of the “secure by default” requirements, when an Exchange 2013 server is installed it is configured with self-signed SSL certificates that are enabled for those protocols.I’ve been using my Synology NAS with HTTPS enabled for a while now but with a self-signed certificate it wasn’t all that secure.Today I decided to try the new feature in DSM 6 Beta 2 for installing a SSL certificate to better secure my NAS. This article is intended for use by System Administrators.
SSL Error 61 can occur when the server certificate is not compliant with the instructions in RFC 3280 regarding the Enhanced Key Usage field.
The system administrator might need to contact the certificate authority who sold the faulty certificate and inform them that the certificate is in violation of RFC 3280.
Also ask the certificate authority to issue a new certificate that contains the following key usage value in addition to any other required values: Server Authentication (18.104.22.168.22.214.171.124.1) Net Scaler Gateway acts as an SSL server, so Server Authentication (126.96.36.199.188.8.131.52.1) must be listed among the designated key uses if any are present.
When you get the this error make sure you didn’t made any typo’s, you created the correct DNS records, and your NAS is accessible via port 80.
When everything is okay your Synology NAS will restart the web server automatically.
