When I am calling my .Net backend from my angular frontend I get the following error: "Http failure response for http:// 0 Unknown Error"

Testing those Backend-Calls with Swagger works perfectly fine and since i have let swaggergen create my services in my angular frontend i asume they are also working.

I have stumbled across Solutions where CORS needed to be added to the Backend Project. After installing and adding the needed CORS lines in the program.cs it still doesn't work.

I have tried simply typing the url into chrome where http://... didn't work https:// delievered the required data but i don't know if that has anything to do with my problem.
