Why am I receiving "SL: CERTIFICATE_VERIFY_FAILED" errors after configuring the "Splunk_TA_nessus" add-on?

[jmaple]

I have configured the SSL certificate according to instructions of the TA.

• Copy the URL of Security Center and paste it to the Firefox browser.
• Click View Page Info > Security > View Certificate > Details > Export as PEM file.
• Copy the content of the PEM file into $SPLUNK_HOME/etc/apps/Splunk_TA_nessus/bin/splunk_ta_nessus/httplib2/cacerts.txt and then save.

I've attempted to append the additional certificate information to the existing file as well as remove all contents except my extracted cert and the result is the same. How am I supposed to add this certificate in accordance with these instructions?

After doing another export of the certificate, I change my "X.509 Certificate" option to be "X.509 Certificate with chain" as we have a cert chain in our environment and the problem looks to have resolved. Now I just have to figure out if the lack of data is representative of no data coming from Nessus or another issue.
