I have a vision client that is taking 10+ minutes to load since upgrading to ignition 8.3.1 (From 8.1).
The issue appears to be caused by the JxBrowser failing to initialise causing the client to hang until an exception is thrown. See logs below.
In 8.1 I had a similar issue which was fixed by disabling the Web Browser Module which would stop the JxBrowser from initialising in the first place. However in 8.3.1 I've not found a way to stop JxBrowser from initialising.
I havent got any Web Browser components in the project, and I've tried disabling the reporting module.
This issue is only present on one HMI I have for dev purposes; the same client opens quickly on my local machine.
Problem machine: Windows 10 IoT Enterprise LTSC 21H2, Intel Celeron N2930, 4 GB RAM, Sentinel Agent + Sentinel Firewall enabled, Windows Defender and Windows Firewall disabled.
I suspect this may ultimately be an antivirus / endpoint protection issue on this particular HMI, but if there’s any supported way to get around the JxBrowser initialisation within Ignition 8.3, that would be my preferred solution.
