I am having three nodes setup in AWS ec2 and it was working fine. Before couple of days, I had to replicate my nodes image to another instance to increase space. I changed IPs in yml file but while starting cluster, i got the below warning.

```auto
[2020-06-26T08:33:24,507][WARN][o.e.c.c.ClusterFormationFailureHelper] [esnode1] master not discovered or elected yet, an election requires at least 2 nodes with ids from [vlvaJ-oXRCKfTVmFMp9qzg, HiQI7ReGTBiJ3Z8_OZW99A, tcRZoGLvTYq5ljMUjY0BDQ], have discovered [{esnode1}{tcRZoGLvTYq5ljMUjY0BDQ}{fN1rDxTKTe64-tYom4yoFQ}{10.10.10.48}{10.10.10.48:9300}{dimr}, {esnode1}{tcRZoGLvTYq5ljMUjY0BDQ}{cLDJXMmQSBS0Dv8Uk2HC8w}{10.10.12.47}{10.10.12.47:9300}{dimr}, {esnode1}{tcRZoGLvTYq5ljMUjY0BDQ}{bNmLsB98RtKJjn5sI6JxNA}{10.10.11.104}{10.10.11.104:9300}{dimr}] which is not a quorum; discovery will continue using [10.10.12.47:9300, 10.10.11.104:9300] from hosts providers and [{esnode1}{tcRZoGLvTYq5ljMUjY0BDQ}{fN1rDxTKTe64-tYom4yoFQ}{10.10.10.48}{10.10.10.48:9300}{dimr}] from last-known cluster state; node term 3, last-accepted version 46 in term 1

```

My Master node has not been elected due to this, please help.
