For the last few days, TotalConnect has been failing with this error:

2025-01-27 07:41:40,638 Thread-996 (poll) udi_interface      INFO     totalconnect-poly:authenticate: Re-authenticating
2025-01-27 07:41:40,638 Thread-996 (poll) udi_interface      ERROR    totalconnect-poly:authenticate: Could not re-authenticate 'NoneType' object has no attribute 'authenticate'
Traceback (most recent call last):
  File "/var/polyglot/pg3/ns/[redacted]/totalconnect-poly.py", line 124, in authenticate
    self.tc.authenticate()
    ^^^^^^^^^^^^^^^^^^^^
AttributeError: 'NoneType' object has no attribute 'authenticate'

(I redacted part of the file path. It was the only part of the message that seemed like it could be unique to me so I took it out just in case.)

Any thoughts?

Same here.  I think they finally blocked us completely.  I am using IFTT plugin for web hook.  No status reporting but at least my programs can still arm the system.
