Diagnostic with CURL.exe: For communication issues with YPS in Sentinel Cloud

In case of YPS communication failure issues we could use curl.exe to check if the YPS address is reachable or not. Simply using ping against the YPS address doesn’t work.


The command that could be used is as follows:


If proxy is NOT configured:


curl.exe –v <YPS_Address> –cacert


If proxy is configured:


curl.exe -v –x <Proxy_Address:80> <YPS_Address> –cacert


curl.exe is an open source and could be downloaded easily. Following is the link for 64 bit version:




This would help in identifying if it is application/configuration issue or some other network issue.
