Hi ,
Thanks for reaching out to Microsoft Q&A.
If you're getting a timeout while fetching data from Azure Event Hub, check the following:
- Network & Firewall - Ensure outbound access to
servicebus.windows.net
on port 5671. - Authentication - Verify SAS policy, Managed Identity, or Connection String.
- Consumer Group & Ownership - Ensure no conflicts in exclusive mode.
- Data Availability - Messages might have expired (default retention is 1 day).
- Quota Limits - Check Azure Monitor logs for throttling or scaling issues.
- Connectivity Issues - Run a telnet test to check connectivity.
- Event Hub Logs - Enable diagnostic logs in Azure Monitor.
Try reconnecting and checking Azure logs for errors. If the issue persists, check network settings and quotas
