You'll have to look in the install directory to retrieve the `wrapper.log` file, and study the errors near the end for clues. Or share with us to help you look at it. Or open a support ticket if the exposure would be a problem.

Please share more information as pturmel mentioned or provide clarification on the below so is easier to isolate the issue accurately:

- Was this screenshot taken from the server/PC hosting the gateway?

- Is the service confirmed to be running?

- Was the service configured to use port 8088?

- Have there been any recent cybersecurity or firewall changes on the computer hosting the service?

- Was the system previously operational, or are you currently commissioning the gateway?

- Is the gateway and projects running but gateway web service inaccessible, or is the entire service stopped?

I think this is a known issue. I presume you do not have Vision installed? Or perhaps it is faulted?

Look for more log entries with 'factorypmi' in them for clues. (Or, open a support ticket.)

FYI I received this same error, it occurred after uninstalling the Vision module on a system running Ignition 8.1.53. I uninstalled Vision because it was just running in trial mode.

Support advised me to restart the Ignition service (which brought back the gateway page), and re-install the vision module.
