When I am on site and connected via Wi-Fi or Ethernet I have zero issues vision client works fine.  
If I am at another plant or using VPN to remote in to the network my vision client hangs (clock stops and pause restarts again)  
If I load the designer and then access any of the screens everything works perfectly.  
Anyone have any ideas?  
I have a few screens that require SQL data pull to update the information but I’m at a loss as to what is causing the vision client to hang.

Any ideas?

The usual cause of things like this are bindings that use `runScript` to call a function that communicates with the gateway, or that do alarm queries or DB queries, and they run slower enough over VPN that you start to notice the UI freeze.

What version of Ignition are you using? In 8.1.12 we added an automatic thread dump that gets triggered when it catches the UI hang for long enough.

I’ll check I think it’s 8.1.11
