Error: Elastic APM server is not available. (It seems like you are using a version of the APM server which isn't compatible with this agent. Please use APM server 6.5 or newer. ).
But from what I have researched so far, APM server 6.5 is not yet released. I am using ELK APM API for monitoring Vert.x application.
Is there something I might be missing out?
