3034029 - SAP HANA cockpit showing blank screen after host name change

After changing host name, HANA Cockpit shows blank page, as below.

"xs env cockpit-flp-content" and "xs env cockpit-web-app" return old host name, like below.

"portal-services" : [ {
 "name" : "cockpit-ps-content",
 "label" : "portal-services",
...

"portalStaticResourcesUrl" : "https://old_host_name.domain_name:51030",
...

"url" : "https://old_host_name.domain_name:51029"
 }

While,  "xs env sap-portal-persistency" returns correct new host name.

"full_application_uris" : [ "https://new_host_name.domain_name:51029" ],

...

portalServices: 
 [
 {
 "name": "portalStaticResourcesUrl",
 "url": "https://new_host_name.domain_name:51030"
 }
 ]

You had followed the steps in KBA 2925674 OR had tried both commands "xs restage cockpit-flp-content" and "xs restart cockpit-flp-content", but the issue persists.
