Read the statement by Michael Teeuw here.
"Invalid Date" appears in Weather module.  MM v2.29.0

 @VinGroot well 401 means apikey not right 
- 
 I figured it out. I use the free plan, so I cannot use API version 3.0. I have to use API version 2.5. Furthermore I have to use the /weather endpoint. I got it working again by adding these 2 settings: apiVersion: '2.5' weatherEndpoint: "/weather"

 @VinGroot awesome

 I have rebuilt my installation and used backup .js files. Everything has worked apart from the weather module. I am getting the ‘Invalid date’ message a temperature of NaN. I have tried adding the apiVersion: ‘2.5’ 
 weatherEndpoint: “/weather”Lines into the config.js file but then MagicMirror doesn’t load. the section of config.sys is: { module: "weather", position: "top_right", config: { weatherProvider: "openweathermap", type: "current", location: "Machat", locationID: "2983291", //ID from http://bulk.openweathermap.org/sample/city.list.json.gz; unzip the gz file and find your city apiKey: "cxxxxxxxxxxxx57f81f9d82849a2fc21a" } }, { module: "weather", position: "top_right", header: "Weather Forecast", config: { weatherProvider: "openweathermap", type: "forecast", location: "Machat", locationID: "2983291", //ID from http://bulk.openweathermap.org/sample/city.list.json.gz; unzip the gz file and find your city apiKey: "cxxxxxxx57f81f9d82849a2fc21a" } },

 @lif are you on 2.29 or 2.30? cd ~/MagicMirror grep version package. json

Not that line but that wasn’t the problem :-) Thanks for the link showing how to subscribe to OpenWeathermap which solved the problem.
