Have been working on setting up a Taxii feed pulling observables in from CISA/DHS however seem to be encountering the following error message which looks like an SSL error:
ssl.SSLError: [SSL] PEMlib (_ssl.c:3954)
I've been digging around but cant seem to find much on this exact error code. Cert and Key files are defined correctly as we use those same cert/key files in a separate technology "MineMeld" which is working as expected. Those files are uploaded into the credential manager and documentation followed under the https://docs.splunk.com/Documentation/ES/6.5.0/Admin/Downloadthreatfeed link.
