I guess Websocket compression was broken in Centrifugo at some point and recently fixed in https://github.com/centrifugal/centrifugo/releases/tag/v5.3.1 - there is exactly the error you've shown.

Current options for you:

• do not use compression (i.e. make "websocket_compression" : false) - may result into more traffic
• switch to Centrifugo v5

Can you do sth from the above?

[sajjad-fatehi]

oops . after spending hours disabling it solved the problem.
thanks a lot .
actually at this moment ill do disable compression because i think migrate directly from v3 to v5 will cause more effort and problems (maybe) .
hmmm can we fix this v4 problem or it is not centrifugo's policy ?

[FZambia]

Sorry, this fix won't land into v4, too much of maintenance overhead at this point. I suggest switching to v5 – the migration to it should be less radical than v3 -> v4.
