Question:
Error "The host name in the certificate is invalid or does not match" when logging into one-click 
Answer:
The system name in the SSL certificate is different then system name you are logging into. Recent changes to certificate authentication require the name to match the name in the certificate exactly. Certificates use the fully qualified host name. You need to use the fully qualified host name when logging into one click for eHealth.
