Regex to allow all WebSocket

Question

I am trying to make a regex exception to allow all WebSocket connections. I used this site ( https://regexr.com ) to test the expression, and it works there, but not in Sophos UTM. Here is my code: 
 ^wss:\/\/\S+(\/\S+)*(\/)?$ 
 I also tried this: 
 ^wss://\S+(\/\S+)*(\/)?$ 
 What do I need to change to make it work? I am testing WebSocket access via this site: https://websocketstest.com 
 Thanks!
