Splunk SSL Error with Python

ws — Mon, 10 Feb 2025 12:17:46 GMT

Hi,

I’m currently encountering the following error message in `splunkd.log` when I enable the custom TA Add-on.

I have a Python script that successfully tests the signed CSR, private key, and root CA. It can establish a connection and retrieve logs as expected. However, when using the application created, I am seeing the error message. I’ve double-checked the values, and everything seems to be the same.

In our testing environment, it works, but the only difference I noticed is that the root CA certificate is in .csr format. Should I convert it to .pem, as we did in the testing environment?

-0700 ERROR ExecProcessor - message from "/data/splunk/bin/python3.7 /data/splunk/etc/apps/TA_case/bin/case.py" HTTPSConnectionPool(host='<HiddenForSensitivityPurpose>', port=443): Max retries exceeded with url: <HiddenForSensitivityPurpose>caseType=Service+Case&fromData=2025-02-06+17%3A23&endDate=2025-02-06+21%3A23 (Caused by SSLError(SSLCertverificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1106)')))

From my understanding (and I admit I might be wrong), isn't a csr a certificate signing request i.e. a request to a CA to sign a certificate, not an actual certificate? Perhaps this might be why you are having difficulties?

My apologies if my explanation is confusing. You are right, the csr has been signed, so right now it's a certificate which is in .pem format.

But the rather, the root ca certificate is in .cer format.

And for my testing environment, the root ca certificate is in .pem format.

My next step is trying to convert it but unsure will it work.
