Memsql-list shows newly added leaf node in DISCONNECTED state

Help
1

I have added a new leaf node(10.162.140.63) using memsql-ops UI, but the node is disconnected from the cluster.
Existing leaf node (10.162.141.12) works correctly.

$ memsql-ops memsql-list
ID Agent Id Process State Cluster State Role Host Port Version
DB381ED A57780e RUNNING CONNECTED MASTER 10.162.141.11 3306 7.1.2

C2C2080 A9af13d RUNNING DISCONNECTED LEAF 10.162.140.63 3306 7.1.2

$ memsql-ops agent-list

A9af13d 10.162.140.63 9000 FOLLOWER ONLINE 6.7.8

Any help would be highly appreciated.

I’d recommend upgrading to a new engine release and also upgrading to SingleStore tools. Memsql-ops is not supported any longer.
