error in the node address

[doronin-a-a]

when creating a cluster of 3 nodes (192.168.1.21, 192.168.1.23, 192.168.2.21) and running services through systemd, I get an error: one of the nodes has an incorrect address and it is not possible to connect to it (192.168.1.21):

csbd-ssnode1.txt
csbd-ssnode2.txt
rcsbd-ssnode1.txt

I checked the settings of /etc/hosts, reinstalled etcd and unit on the problematic node, also tried reinitializing the cluster with a new name, but the error remains active, please tell me where else can I check the settings and what can I do?
