We are using Release Automation version 184.108.40.206, and we have an execution server. And since 2 days it is not reachable. We tried restarting the server, and in server level it shows it is up and in RA level it shows it is in offline status only.
We have validated with Network team, and everything is fine from their side. Kindly provide inputs on how to resolve the same.
Release : 6.6, 6.7
Component : CA RELEASE AUTOMATION RELEASE OPERATIONS CENTER
The error means that this execution server is connected to some other NAC.
2020-11-27T08:57:46.359+01:00 [ReverseConnectionWorker-1] INFO (com.nolio.nimi.comm.impl.NetworkConnectionManagerImpl:139) -Found existing connection to address [l*******/X.X.X.X:6600] for node [nid:es_****].
The above method means this NES is already connected to some other NAC in your environment. It is as per design a NES can't be connected to more than 1 NAC
The way to resolve this is as below
1: Locate the NAC where it is connected and remove this execution server from there and than re-add it to the NAC you want to see it as online.
The below steps will force to clear all connection data with any other NAC and should start a fresh.
