FoxESS Community - Owners & Installers Forum

Hi,

I am curious if anyone else is experiencing this but since Saturday afternoon (Toronto time) Jan 17 2026, my API calls are running into {'errno': 41200, 'msg': 'Unrecognized msg:41200', 'result': None}. I checked that I have plenty of API limits left as well as a valid API key. Worth noting that my api key comes from portal.foxesscloud.us NOT foxesscloud.com (which doesn't work for Canada)

I read somewhere this usually indicates cloud problems on Foxess end, but not sure

any thoughts/help appreciated

thanks

Simon

As an update, I noticed that I CAN make calls to the power station endpoint, e.g. `/op/v0/plant/detail` but once I try to make calls to the inverter or hub, they all fail with the aforementioned error. And this used to work just fine. I have to believe the issue is in their backend perhaps when communicating with the system to get and set details on the actual inverters but I am speculating of course.
