Alexa Dont Work

[DGrandes]

Hi,

I´ve been working with alexa for one year and since a week don´t work. Alexa recive the order and say OK but in Logic Machine don´t change the object.
I´ve tried to disconect cloud from my LM and conect to another logic machine and work fine.
I see in error log the following error (In my LM): 
Script name: Alexa --> Error description: Line 777: MQTT.clientubscribe(): Not connected

Any idea?

Thanks
