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 certificate

this 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.

You could try and disable Use SSL in the monitoring configuration.
