Hi Kalinka, sorry you are running into issues. It's hard to tell what website you are trying to access with the websocket from this error log, can you post that here? My guess is that you are using a ws:// connection, when it needs to be a wss:// connection. ws:// is an insecure websocket connection (akin to http) vs wss:// is a secure websocket connection (similar to https). The browser will stop you from making an insecure websocket connection from a secure (https) connection, which I think is what you are running into here. The fix should be to change ws:// in your websocket url to wss://, unless I've misdiagnosed the issue.
If that doesn't work, can you please post your code around setting up the websocket to help diagnose the issue?
