FIORI search is not working GetServerInfo is failed

Hi Experts,

FIORI search is not working due to GetServerInfo is getting failed.

Backend search connector has been activated using ESH_COCKPIT and Webdispatcher is configured as given in configuration guide.

Earlier fiori search is working fine but after upgrading UI version to 1.28.31, fiori search is not working as expected.

Screenshot of Network tab in console of google chrome.

Here status is set to 401 - Unauthorized. But respected user has all the authorization.

Kindly provide suggestion to resolve the same.

Regards,
