Issues loading demo Perspective project

Ignition

I get a similar error to Paullys50 except that mine says “WebSocket handshake: ‘Connection’ header value must contain ‘Upgrade’”. We have a Sophos UTM 9. I updated the filter options exception list to not block anything from the following URL regex expressions but it doesn’t seem to have done the trick:

  1. ^http?://demo.inductiveautomation.com/.*
  2. ^ws?://demo.inductiveautomation.com/.*
  3. ^wss?://demo.inductiveautomation.com/.*

Maybe I’m missing some URLs or an improper regex expression?
