How do I resolve this error: MISP APP API SSL: CERTIFICATE_VERIFY_FAILED

[gordonblei]

Hello,

i have setup the  MISP42 | Splunkbase app and i want splunk to use the ssl connection to MISP.

My certificate is issued by lets encrypt for MISP and SPLUNK. 

i have copied the fullchain.pem and crt from MISP to SPLUNK

But is still get the following error after enabling "check MISP certificate" 

External search command 'mispgetevent' returned error code 1. Script output = "error_message=SSLError at "/opt/splunk/lib/python3.7/site-packages/requests/adapters.py", line 514 : HTTPSConnectionPool(host='FQDN', port=443): Max retries exceeded with url: /events/restSearch (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get issuer certificate (_ssl.c:1106)'))) ". 

Thanks in advance for your help

Had you resolved this issue? 
I had the same problem. I just export the Certificate form MISP and added it to splunk python CA store.
