Failing health checks - Failed SSL Negotiation
Real Server is failing health checks, found "Failed SSL negotiation" in the log files.
Application: Any web-based application
What do "Failed SSL negotiation" log messages indicate?
|Steps to Reproduce:|
|Error Message:||Failed SSL negotiation|
HTTPS Protocol health checks are in use on the VS/SubVS indicated within Virtual Services > View/Modify Services > modify the indicated Virtual Service > if necessary, modify the indicated SubVS > Real Servers.
This message indicates that the underlying TCP connection is able to form as expected, but the SSL handshake is failing.
|Resolution:||A packet capture should be taken from the LoadMaster to determine why the SSL handshake is failing. This can be done by navigating to System Configuration > Troubleshooting > populate the Real Server address in the Address field > Start > wait one minute for health checks to run > Stop > Download. Open the file with a tool such as Wireshark.|
