Fix for problems with current Safari release

We are aware that VFB’s secure websocket connection is failing to connect on the latest version of Safari on MacOS meaning that no data can be pulled from our servers.

The issue is down to an ’experimental feature’ (NSURLSession WebSocket) being set to ON by default which seams to break most sites using secure websockets.

To turn resolve this issue turn this off:

In Safari on the desktop:

 Under 'Develop' expand 'Experimental Features' untick 'NSURLSession WebSocket'

If you don’t see the Develop menu in the menu bar, choose Safari > Preferences, click Advanced, then select “Show Develop menu in menu bar”. Restarting Safari may be necessary if the list of features under ‘Experimental Features’ are greyed out.

On IOS devices:

 Open the Settings app

 Scroll down and tap on “Safari”
 
 Scroll down to the bottom and tap on “Advanced”
 
 Tap on “Experimental Features” at the bottom
 
 Scroll down until you see “NSURLSession WebSocket"
 
 Disable “NSURLSession WebSocket”
