[MQTT] locks up when set authentication and client ID.

I'm using the Wio Tracker
(Wio LTE Cat M1/NB-IoT Tracker)

I can connect to an Azure MQTT server when it does not require authentication. I'm trying to test it using an authenticated MQTT server, but when I try to set authentication or set the client ID, I simply get no response.

Thus far, I'm thinking the main culprit is the length. I am sending "AT+UMQTT=4, "user", "password", and with the actual username and password entered, the string ends up over 160 characters, and includes spaces and a full URI. The strange part is just that I get NO response. Having worked with modems in the past, a bad command will return an error, but there was very little that could return a blank.

Any ideas what could be going on?

EDIT: OK, shortening the username and password allows authentication to pass. Set Client ID returns a failure right away, though.
