The cause of errors in production Assembly in Angular?

When I build my project no errors, collects all fine. But when everything is assembled, try to open a file index.html and out of the error:
1. Refused to apply style from 'http://localhost:63342/styles.71f283d32a5001186b60.css' because its MIME type ('text/html') is not a supported MIME type of the stylesheet, and strict MIME checking is enabled.

Solution
With some servers you open the project?
<base href="/"> in index.html existents?
The project is locally assembled. Yes there is. - darryl_Friesen commented on April 7th 20 at 15:46
@ari_Medhurstto open localhost:63342 need to have some server gave the content when you request to port 63342.
so I ask, what server? - gracie_Bailey commented on April 7th 20 at 15:49
@rickey19, thanks, the problem was in the settings of Jenkins. - darryl_Friesen commented on April 7th 20 at 15:52
