ClusterUpdateError

Description of problem:
We have created the OCP cluster (version 4.8.39) with dual stack cluster network,
we have the VM interface which is configured with ipv4 and ipv6 on all nodes(3 master node and 2 worker node).
Cluster installation is working working fine.

But cluster update from 4.8.39 to 4.8.31 is not working fine.
Cluster update is stuck at Partial state, with below failing reason,

"
EtcdCertSignerControllerDegraded: [x509: certificate is valid for 10.30.1.4, not 2101::4, x509: certificate is valid for ::1, 10.30.1.4, 127.0.0.1, ::1, not 2101::4]
