Plugin startup errors

I'm seeing errors with the plugin. Not sure what changed to cause this. The iOS app seems to be working fine. I've tried reloading the plugin, reinstalling the latest version, restarting Indigo. Same behaviour

'Connection Refused' often means the IP address is wrong. Could the Heatmiser hub address have changed? If not, in Config, check the box 'Copy Neo comms to Indigo Event Log' and PM me with the results; I'll have a look.

Here's the solution, for anyone else who faces the problem.

Early in 2022, Heatmiser updated their API and provided support for the 'legacy mode'. That legacy API turns off after 48h if not used, and can be re-enabled using a switch in their app (on iOS: Settings->API-> Legacy API switch). I had disabled the plugin previously for some reason (I forget why) and the 48h timer then expired.

I then found that the Neomiser plugin wasn't able to connect even after re-enabling the API. And also that the API reverts to a disabled state within minutes. However, enabling the legacy API, and immediately opening a telnet connection on to the hub on port 4242 was enough to re-open the connection properly, reset the 48h timer and thereafter the plugin connects just fine.
