Disabling proxy settings in Android Studio 3.2.1 not working

Sometimes I am working in internal network and have to setup proxy settings in Android Studio now I have changed the network and need to disable proxy settings to be able to download dependencies.

But somehow I can't disable proxy configuration. Android Studio is still trying to connect through proxy. Here is what I did to disable it;

1. Removed http and https configuration in gradle.properties / local.properties.
2. Disabled proxy configuration in Preferences-> System Settings-> HTTP Proxy.
3. Removed operating system proxy settings in network.
4. Uninstall & install Java
5. Uninstall & install SDK
6. Uninstall & install Android Studio

Unfortunately none of above steps and the answers in community worked. Feeling so desperate :)

Here is the screenshot of Android Studio. My final choice will be formatting macOS.

I think you have global properties for proxy settings. You can check the global gradle properties from here.

We can define a gradle.properties file and set the property in this file. We can place the file in our project directory or in the <USER_HOME>/.gradle directory. The properties defined in the property file in our home directory take precedence over the properties defined in the file in our project directory. As a bonus we can also define system properties in a gradle.properties file, we only have to prefix the property name with systemProp..

Global gradle proxy settings?
