What version are you using? Synchrony needs websockets for the two way communication. It'll try on /synchrony first if your reverse proxy is configured to support the upgrade. Then //synchrony-proxy and finally if the property is set it will fallback to XHR.
If your LTM is using an HTTP profile and it's less than 11.4.0, you'll need to not use the HTTP profile. 11.4.0 is when F5 added the websocket support, see: https://devcentral.f5.com/articles/load-balancing-websockets
