Node fails when trying to connect with Akka remote

[Danny Lesnik]

I've frontend and backend server. 

Frontend runs Play! 2.5 and akka 2.4.11

Backend runs akka 2.4.11

Both running kamon 0.6.3, 

and has the following dependencies: 

"io.kamon" %% "kamon-akka" % Version.kamon,
"io.kamon" %% "kamon-log-reporter" % Version.kamon,
"io.kamon" %% "kamon-system-metrics" % Version.kamon,
"io.kamon" %% "kamon-core" % Version.kamon,
"io.kamon" %% "kamon-akka-remote" % Version.kamon,
"io.kamon" %% "kamon-statsd" % Version.kamon,
"io.kamon" % "kamon-play-25_2.11" % Version.kamon

In build.sbt I have the following:

aspectjSettings
javaOptions <++= AspectjKeys.weaverOptions in Aspectj
fork in run := true

I'm starting backend with the aspectj weaver:

-javaagent:./aspectjweaver/aspectjweaver-1.8.9.jar

In plugins.sbt I added the folllowing plugin:

addSbtPlugin("io.kamon" % "aspectj-play-runner" % "0.1.3")

However when I start backend and frontend, I'm getting the following exception immidiately as my frontend node joins 

backend cluster.

Can you please help?

Hello Danny,

Could you please try using "kamon-akka-remote_akka-2.4"? It you are using Akka 2.4 you should change to this one. Please let us know if the problem persists after the change, regards!
