Content security policy is set, but errors still occur

Hello all

I have the problem that I get CSP errors in the browser console and the content is not loaded properly although a CSP is set that allows the subdomain through which I make the call.

I added the following line to the end of httpd.conf and restarted the webserver.

Header set Content-Security-Policy “default-src ‘self’; connect-src https:/mydomain; script-src ‘self’ https:/mydomain; img-src ‘self’ https:/mydomain; style-src ‘self’; frame-ancestors ‘self’; frame-src ‘self’;”

only one / is set after https: so the forum lets me post it.

Chrome console output:

What am I doing wrong?

If more information is needed, please tell me.

I have screenshots of the response headers if needed.
I may attach only one screenshot for this post as a new user.
