Issues with Qualys Technology Add-on (TA) 1.5.1 unable to fetch data

Hello All,

We are facing issues with our Qualys Technology Add-on (TA) 1.5.1 where it is unable to fetch any data ( host detection/knowledge base ) from Cloud api.

ta_QualysCloudPlatform.log:

Configuration:
Qualys TA has been installed in both Search head and heavy forwarder as per the Qualys guidelines
Host_dection input has been enabled in HF and KB input enabled in SH

Configuration on SH:

The api pull works when done via curl command using the same certificate/credentials and proxy from the same server just not happening from qualys add-on.

Any suggestions will be appreciated
