Hi everyone here!

I'm doing my first customizations for QRadar version 51.0.6.0.20381 

When I try to configure #Connectors, the one of them - to BackStage Catalog API, following  Procedure of Creating custom connector functions for playbooks I've got the error:

The error remains the same independently from the chosen Security scheme

In server logs I've got followinf stack trace:

What is the reason of such error?

Thank you for any hint in advance!

Maksym,

a German saying says "the computer is always right". This is true in this case as well. Your URL should be a FQDN according to the documentation and error message shown. Unfortunately its not fully shown in your greyed out screenshot but I am quite sure this is the problem. Another connector issue is that your connector URL should be up and running and reachable from your system. The easiest way to test this is to copy your URL into a curl command and test it from CLI if you receive a code other than 404.

Karl, 

thank you.

In fact, curl'ing URL mentioned in Connector settings from Qradar host is working just fine, while the same from App Host fails with:

curl: (60) SSL certificate problem: self signed certificate in certificate chain

I'm not sure if this is the same cause I have with Connector settings.
