Cookies are not set after Authorization on my SPA

Hello all,

unfortunately my SPA application in Angular does not set cookies after successful authentication. After logging in, I am redirected to the specified callback url of my app settings. Or rather the url are then like this :
http://localhost:4200/?code=IsuhoiGZl_0_5xc238fgx7x7YaOcfMmlATdAtzu55r13p&state=YjdpMzd4bl9EZ2ZwZ1NVTGlGZmw0YmFnOEluSjdTdTRwbUp6OUVWNTVzRQ%3D%3D

No cookies are set in the browser and I don’t know how to fix the problem. I have read several posts from this forum and tried to apply the solutions, but none of them worked for me.

I also tried the sample application on my end and ran it with my app settings. Cookies were set there. And the And the application ran successfully.

Has anyone here had similar problems before ?
