frame not masked so close the connection
I had the same problem.
there were such errors:
_frame not masked so close the connection_
or
_error opcode XX and close websocket connection_
it turned out to blame was mbstring
in particular, strlen (), which when enabled "mbstring " begins to measure not bytes but characters.
To solve this need in php.ini set
mbstring.func_overload = 0
