Updating IBM MQ Extension to the latest version - 4.3.4
We are getting this Error Message
Endpoints OK: 0 WARNING: 0 ERROR: 1 Unhealthy endpoints: <Queue Manager> - GENERIC_ERROR DEC:159 Failed to communicate with tenant https://127.0.0.1:9999/e/<Tenant ID>/api/v2/settings/objects.

Hi,
It looks like the issue is not directly related to the IBM MQ connection itself.
The error occurs when the extension tries to communicate with the Dynatrace Environment API through the local ActiveGate endpoint.
CERTIFICATE_VERIFY_FAILED: self-signed certificatethis looks more like a certificate trust issue between the extension and the local ActiveGate, or potentially a regression introduced with IBM MQ Extension 4.3.4 if the previous version worked with exactly the same configuration.
If the previous IBM MQ Extension version worked on the same ActiveGate without any certificate changes, I would suspect an issue introduced in 4.3.4 and recommend opening a Dynatrace Support case.

Hi @mindscratch
This is a known issue with extensions running on ActiveGate, the extension process tries to call the local ActiveGate API (127.0.0.1:9999) but fails SSL verification because ActiveGate uses a self-signed certificate by default.
Reason
The IBM MQ extension communicates with the local ActiveGate REST API on https://127.0.0.1:9999 to push settings/objects. When ActiveGate is using a self-signed certificate, the Python SSL layer inside the extension rejects it with CERTIFICATE_VERIFY_FAILED. This is typically triggered or exposed after upgrading to 4.3.4 if that version introduced a new API call to /api/v2/settings/objects.
Solution: Replace the ActiveGate self-signed cert with a trusted certificate.
Thanks,
Sujit
