Hello Community,

I am following the Spring 2025 Workforce webcasts and I am having problem doing a sync of either AD Users or AD Groups. Whenever I tried to sync it always give me this error message: “Error code: INTERNAL\_ERROR;Error Text: Response is not received from RabbitMQ during reply timeout”.

I have deployed 2 VMs, one Windows Server 2019 AD DC and a Centos Stream 9 Openiam server and has disabled firewalls on both servers. All VMs are connected to the same virtual network.

I have tried the solution provided in this link [Connector troubleshooting](https://docs.openiam.com/docs-4.2.1.13/connectorconfig/4-troubleshootingconnector/) and am still unable to fix the issue. Any advise on how I might be able to resolve this issue?

Hello @Coad,

Could you please provide the following:

1. Screenshots of the configuration changes (as per the connector troubleshooting guide), so we can validate the setup.

2. Synchronization logs and ESB logs for further review.

Thanks,

Ameet

Hello @ameet_shah,

Sorry for the late reply I have managed to resolve the issue already. The problem was due to the hostname not being able to resolve.

Appreciate you for reaching out to me.  
Thanks,
