Joining cluster failed

Common reasons

  1. You haven't performed sudo anka license accept-eula
  2. The controller URL doesn't include the port.
  3. The AnkaAgent is out of date. Perform curl -O http://**{controllerUrlHere}**/pkg/AnkaAgent.pkg && sudo installer -pkg AnkaAgent.pkg -tgt / to update it.

Solution

Try one of the above common reasons.
