Access to XMLHttpRequest at 'http://68.183.74.23:5000/api/post_data' from origin 'http://68.183.74.23:8000' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.
CORS policy does not allow sites to access data from another domain in a suspicious manner, we have to fix this to be able to get data from the flask-server without having the CORS-extension installed.
