HI,

does anybody has a clue, what causes this error message, which pops up in my console permanently?  
Thanks!

Frank

That usually means there’s a deep inspection firewall in the way that is killing off connections that it doesn’t understand. Ignition Perspective uses websockets, which start as HTTP(S) and then “upgrade” to WS. Some older firewalls don’t understand that upgrade process. Some might have it deliberately turned off, I suppose.
