Gateway Unreachable

Hi pdolan_tapco ,

Try below things to fix the issue.

1.  On the gateway machine: restart the service

On-premises data gateway → Restart

2. Run Diagnostics

Gateway app → Diagnostics → Verify:

Cloud connection = Success

Service Bus = Success

3.  Ensure outbound ports are open

Your network/firewall must allow,

443, 5671–5672 and Wildcard domains.

4. Check Gateway Cluster Health

Power BI Service → Settings → Manage Gateways

All nodes must be Online

Remove/disable any "grey" or "Not Connected" nodes.

5. Check if a VPN is active

VPNs often break scheduled refresh because they intercept AMQP.

If using VPN Exclude gateway traffic Or run gateway on a server that is not behind VPN.

If my response as resolved your issue please mark it as solution and give kudos.
