Cannot Send payload - Connection not established!

[kanni-grand]

I have a connection problem. I tried to use the code from the example but it says to me that. Cannot Send payload - Connection not established! But does not indicate an error. I tried to use an atorted connection. The result was the same. I tried to run from the development of the pyharm. What could be the problem?

Yep I am having this issue too.

Just installed the module with pip and ran this as a test script and got the error which is coming from the Connector class

I added in my api keys to see if it was an authentication problem but this made no change to the response

I'm not sure if this is relevant but I'm using Python 3.6 on this, pehaps thats part of the issue?

The issue stems from breaking changes in websocket-client library. Version 0.49 in particular. The current workaround is to install version 0.48 of websocket using pip: pip install -Iv websocket-client==0.48

Try to run the example: (downgraded websocket-client from 0.57 to 0.48) but no effect. I'm not authenticated because it's a public api ...

Set a time.sleep(10) of at least 10 seconds after you open the websocket connection
