A classic gotcha in the world of ADC load blancing with SSL, manifests itself in two ways:
- LB Servers are added using FQDN. The monitor reponse reports: “domain name not resolved”.
- LB Servers are added using IP. The monitor response reports: “Failure -TCP connection successful, but application timed out”.
|Domain name not resolved|
|Failure – TCP connection successful, but application timed out|
Simply, turn of (untick) “Enabled Health Monitoring” or “AppFlow Logging”.
