No access to wss://website.com unless port 443 bypassed

Question

Hi everybody, 
when I try to access a particualar website which uses websockets (wss://website.com), the request is blocked by the firewall. I tried setting an exception for this particular website in the webfilter with no success. If I bypass all traffic on port 443, the website works. 
Are there settings/exceptions possible that are less radical? 
 
Thanks in advance and kind regards, Ken

This is expected. WAF has added support for websockets in recent releases, but Web Filtering has not. Web Filtering supports HTTP, HTTPS, and FTP protocols only. You need to create a bypass for this site. 
 In Website overrides, create a TAG named "Bypass All" and assign it to your website. 
 In Exceptions, create an exception object, check all the boxes, and configure it for "Going to websites tagged as" tag="Bypass All". 
 This approach worked for me for both Standard and Transparent mode. My best guess is that your first attempt at an exception either had a Regex error or insufficent exceptions.
