Connector to Zeebe-Gateway Timeout issue on Self-Managed Camunda 8.3 on Openshift

Hi,

We have a Self-Managed Camunda 8.3 Setup done on Open shift.
All the components are configured and also able to deploy the process models through desktop modeler. Now in the process model we have a Rest Outbound Connector and all the process instances are stuck at this node.

On checking the Connector pod logs, I See a timeout issue in connecting to Zeebegateway. Below are the logs.

The same gateway host works fine for desktop modeler and also spring boot zeebe client.
