I have upgraded my cluster from 5.5 to 6.1 recently and trying to upload license for the searchguard. I used License Reference Number from license certificate but throws an exception as shown in image. I could see that there is an option to upload license file but don’t have the files apart from License certificate, May I know how could I get the license file for searchguard.
Search Guard - 6.1.3-20 and Elasticsearch 6.1.3 version
Installed and used enterprise modules
JVM version and operating system version
- JAVA 8
