org.jvnet.hudson.reactor.ReactorException

If you like a tip written by other Samebug users, mark is as helpful! Marks help our algorithm provide you better solutions and also help other users.
tip

Try changing the port in core-site.xml from 9000 to 9001 as it seems port 9000 doesn't work.

tip

Change the connection port and ip adress. If you're trying to connect to your server from your own computer, check if you haven't already connected to the server in another instance.

tip

It might be that there's another process connecting to the same port you're trying to use, try to kill it or change the connection port.

You have a different solution? A short tip here would help you and many other users who saw this issue last week.

  • We have another service running on 8081 on a jenkins-master. Enabling the Websocket Plugin leads to a crash after restart with the stack trace [1]. The config does not contain any entries for the plugin yet, so no manual change of the port is possible (without guessing the correct xml).
