system ID mismatch, node belongs to a different cluster

I have etcd cluster, and now trying to initialize patroni (on server A and server B), but whenever I try to do so I'm getting the error about cluster mismatch. Tried removing 'initialize' from etcd, tried completely clearing up etcd saved configuration, but none worked So if I will start patroni on server A, it will successfully initialize, but if I will run it on server B, it will fail with that error. The first who initializes wins, I could say ___ Patroni on server A (B has the same but with different placement of addresses):

How can I fix this? I've faced this issue several times back then (couldn't fix)
