Timeout error after upgrading to Ignition 8.3.7

Hello,

I upgraded our Ignition system from version 8.1.52 to 8.3.7 last night. We have one central Gateway connected to five I/O Gateways.

I upgraded all of them, but something went wrong on one of the I/O Gateways. When I try to change any settings, a timeout error appears. However, the changes are still applied and visible in the Gateway.

I do not experience this problem on any of the other Gateways, and the migration completed successfully on all of them.

What could be causing this issue?

Best regards,
Michał

The error is just the "frontend" (the code running in the web page you're looking at) giving up on waiting for the "backend" (the actual Ignition gateway) to finish, due to some likely hardcoded timeout. That it's taking longer than whatever arbitrary threshold we decided on is potentially concerning - it could be an indicator that the gateway is struggling for some other reason(s).
