X1-C SSL connection failed

The error:

Starting bambulabs_api example
Connecting to Bambulabs 3D printer
IP: <real_ip_here>

Access Code: 81f8c799
ERROR:root:Failed to execute function: 522 SSL connection failed: session reuse required

    if "226" not in result:
       ^^^^^^^^^^^^^^^^^^^
TypeError: argument of type 'NoneType' is not iterable

I have tried the main, x1_camera, and x1_local_ftp branches. The above error is from x1_camera (main produces the same result) as that has resulted in the best output. The code used is the sample code replacing .connect() with .mqtt_start().

The x1_local_ftp branch results in the following error message:

we don't have facilities to directly test X1 printers unfortunately. Could you check if #151 works

[amuhak]

#151 seams to be the same as x1_local_ftp which I tested above. I would be happy to test any additional changes on the X1C and report back.
