Hi everyone,
I’m encountering an issue with a new client machine provided by our IT department.
The client can access the Ignition Gateway web interface without any problems, and every other machine on the network can connect to both the Gateway and our Perspective applications seamlessly. The issue occurs exclusively on this specific client.
When attempting to launch a Perspective project from the navigator, the application gets stuck on the loading screen and eventually fails during the WebSocket handshake, throwing an HTTP 503 (Service Unavailable) error.
We’ve reviewed the Ignition Gateway configuration and found no anomalies. Since all other clients connect fine, the Gateway itself doesn't appear to be the problem.
My suspicion is that an endpoint firewall, proxy, SSL inspection, or another network security policy on this specific machine is interfering with the WebSocket connection to the Gateway.
What potential causes should we consider, and what troubleshooting steps or tools would you recommend to pinpoint the issue?
Thanks in advance for your help!
