Octopus Energy stopped working: no current log

I have problems with my Home Assistant setup and can’t track down where the problem is. Firstly I should mention that my Octopus Energy integration worked along with everything else for the first year or two of installation but has now stopped. I got energy readings until 28 October but not after that, and I can’t attribute this to an upgrade without knowing where these would be logged. An add-on called log viewer used to show the most recent errors in HA with date and time but now just shows the following.

return self._sock.recv_into(b)
  File "/usr/local/lib/python3.13/ssl.py", line 1304, in recv_into
    return self.read(nbytes, buffer)
  File "/usr/local/lib/python3.13/ssl.py", line 1138, in read
    return self._sslobj.read(len, buffer)

I’m puzzled that the directory listing below doesn’t show a file called home-assistant.log and that there seems to be no current log (that is, last updated Nov 21), even in the .fault file.

I’m running the following on an Intel X86 NUC:

Installation method Home Assistant OS
Core 2025.11.2
Supervisor 2025.11.4
Operating System 16.3
Frontend 20251105.0

Any ideas?

The way home assistant logs was changed in 2025.11 and this was mentioned in the release notes and discussed extensively in the release thread comments, you’ll have to adjust.
