ERROR: [notify_error] Unable to retrieve board information. Connection Error?

Is this still a issue?
After flashing this code, the module becomes unavailable via wifi for the espruino ide. There is a connection only through com port. What's the problem, help.

If you load the code without the MQTT library, everything works fine

Connecting...
Set Slow Write = true
Failed to open socket 192.168.0.121:23
ERROR: Unable to open device (connectionInfo=undefined)
