Real server failing and not returning the Reply Pattern - "Response did not match"
Real server failing health checks due to "Response did not match".
Need assistance understanding health checks for a real server that is marked as down.
|Steps to Reproduce:|
|Error Message:||Removing RS <RS IP>:<Port> from VS <VS IP>:<Port> - Response did not match|
|Cause:||The Reply 200 Pattern is not found during health checking of the real server marking it as down.|
When Use HTTP/1.1 is enabled within the virtual services health checks and the HTTP Method is set to GET the Reply 200 Pattern option appears.
If the LoadMaster finds the pattern in the response, the Real Server is considered up. The Real Server is marked as down if the string is not found.
This can also be tested when browsing to the real server IP address to see what string is returned.
The real server will need to be investigated to see why it is not returning the proper string.
