The problem is from Master A (node02) as you can see A thinks there is no leader for this election even their election cycle is same (218). suggest you to check the Master log on A (node02) host to understand why A failed to elect a leader just like other nodes (B and C think that B is the leader)

The consensus matrix is:
Config source | Replicas | Current term | Config index | Committed?
---------------+--------------+--------------+--------------+------------
A | A B C | 218 | -1 | Yes
B | A B* C | 218 | -1 | Yes
C | A B* C | 218 | -1 | Yes
