Hello,
Can you post TMOS version and any relevant ASM event logs when a WSS is made? Can you provide more details on your VS configuration as well? Quick search shows ASM/WAF in relation to WebSocket.. The BIG-IP ASM system fails to detect WebSocket URLs. Also you might want to review this other community article which might address this issue:BIG-IP WAF Causes WSS Connections to Stall | DevCentral

Do you have a websocket profile enabled on this VS? If not please add one and re-test

It is usually a missing websocket profile.
