but my server use EIO=3

Solution

  • You cannot set the EIO parameter directly, you have to use versions of the python-socketio and python-engineio packages that are compatible with the protocol version that you need.

    See the version compaitiblity table in the documentation. The value of EIO is shown in the engine.io protocol revision column.
