Android Studio behind the proxy

Question

I know this type of questions is around since many years and I tried each and every solution with no luck.

I am trying to setup development environment with Android Studio with Flutter. I am keep getting error regarding the certificate.

sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

I tried to change https to http in the gradle prop file and also tried to change from jcenter() to maven but it is not working. Also I tried to import the certificate using the KeyStore Explorer , it says successfully imported but throwing same error when I am trying to run the project.

What went wrong: A problem occurred configuring root project 'android'. Could not resolve all artifacts for configuration ':classpath'.

I talked with my admin team and they are asking for which URLs they need to white list in order to make the flutter work. Let me know if you know what to be white listed.

Answer 1

If you're behind a proxy at work, your Server Team may be blocking certain file types. That's the case for me as I don't have any of these issues when working from an outside line.

Try copying and pasting the link into a browser and look at the error message.

Alternatively, you could try emailing your Server Team and have them open it up for you (temporarily).
