Got unexpected response error (etcdserver: request timed out)

[rkazak07]

Hello,
a cluster structure with 3 nodes has been created
3 pcs etc version: 3.3.27
3 versions of postgresql 14.5
I have set up a cluster structure for 3 Haproxy.
I'm getting the following error. I have set up 0 presentations again because I think it is related to my organization and I am getting the same error again. how can I follow a path related to etcd synchronization disorder
