Why Is Access to Backend Servers Still Abnormal Even If I Have Created a Certificate?

The following are possible causes:

• You have created a certificate on the ELB console, but you do not have an HTTPS listener.

  To solve this problem, perform the following steps:

  • Continue using the current listener and install the certificate on the backend server.
  • Delete the current listener, add an HTTPS listener, and bind a certificate to the HTTPS listener.
• You have created a certificate on the Certificates page and are using an HTTPS listener, but you have not bound the certificate to the listener.
• Your certificate has expired.
• The domain name is different from the one specified when you create the certificate.
• A certificate chain is used, but its format is incorrect.
