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
