what can i do about this ? i've just installed android studio , when i try to create a new project i get an error( first picture ) . i'm forced to use a proxy since i'm living in iran but the connection is successful. i toggled the agp and gradle version but nothing changes. when i use --scan i get another error ( second one).

Well, if you need to use a proxy, you need to configure it. See here for more information: https://docs.gradle.org/current/userguide/networking.html#sec:accessing_the_web_via_a_proxy

Adding the proxy to gradle.properties didn't change anything, still getting the same error And weirdly none of the repositories doesn't even exist when i copy their urls in a browser

That the 2. and 3. do not have the artifact is normal. The first should have them though. But whatever that screenshot is from, it does not look like Gradle output, so the proxy declaration for Gradle might not work for those.

The screenshot is from Android studio, you are right the first one is working in browser but not inside the IDE , i have also set the proxy setting in the IDE but still not working, ty anyway for responding, guess i should look for this problem somewhere else.
