@ereborinkorppi it would be interesting to see the 32 bit results…

ereborinkorppi

@sdetweil I will give it a go if no easier solutions available, but will take some time before I can test it. Thank you so far, will report later what happened.

sdetweil

@ereborinkorppi i just don’t know… we are not using GPU, that error is related to GPU.
says happening in chromium, but we are not using chromium… so… at a loss.

I see it on my pi3 in 32 bit mode, but it doesn’t stop mm…

@ereborinkorppi sorry I hit the reject button, can u resubmit.

Hi I’m a nooby, I’m seeing the same errors in my startup but MM still runs OK. The only reason I found it was because I can’t get the MMM-OpenWeatherMapForecast to display just says loading?
I’m wondering now if the error has nothing to do with module running.

sdetweil

@eyesallin do you see any errors from openweathermapforecast in the place you start mm

Thanks for information

sdetweil

@fethiyetours can u edit the module node_helper.js and change the error path like this

                    } else {   /// this is the current line 62
                        if(response.statusCode != 200)
                            console.log("[MMM-OpenWeatherMapForecast] " + moment().format("D-MMM-YY HH:mm") + " statusCode " + response.statusCode);
                        else 
                            console.log("[MMM-OpenWeatherMapForecast] " + moment().format("D-MMM-YY HH:mm") + " ** ERROR ** " + error);
                    }

I’m guessing the statuscode will be 401, unauthorized
