I am working with a Windows 10 OS and when I run 'yarn start' my app builds succesfully and aparently server is running. Nevertheless, when I connect in a browser to localhost I have the following warnings and errors that I don´t know how to fix. I have just started working with this one week ago so I am not used to It.

If anyone knows what is happening I will be waiting for your response.

are you sure you have the right port? (Like localhost:port) – FredTheDoggy – 2019-09-18T17:24:58.230

Yes, I am sure I have right port because when I run the server It says: Server running on port 4200 – user1091547 – 2019-09-20T13:06:25.227
