Kibana UI issue after upgrade to kibana v7.10.2

After I upgrade Elasticsearch and kibana to v7.10.2 from 7.8.0, I have observed an issue in kibana UI. When I reload the kibana UI after upgrade it gives “ERR_TO_MANY_REDIRECTS” error. Please refer below screenshot for the error.
Note: This is only observed when cluster is up with keycloak and istio.

If I clear browser cookies and retry, this error is not seen. Please explain why this issue is observed and how to overcome this.
Thanks in advance.
