Curl Command SSL Error on Search Head

[harishsplunk7]

We have a total of five search heads, and while four of them are successfully executing the curl command, one search head is encountering an SSL error, specifically a SSLError with a curl status of 408. 

HTTPSConnectionPool(host='localhost', port=8801): Max retries exceeded with url: /servicesNS/nobody/alert/saved/searches/alert/acl (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate in certificate chain (_ssl.c:1106)')))

what is the  next steps to identify and resolve the root cause of this SSL error.

The cause is in the error message: "certificate verify failed: self signed certificate in certificate chain".  Make sure all of the search heads have the same PEM file.
