Emulator: emulator: WARNING: Could not connect to

Emulator: emulator: WARNING: Could not connect to proxy at ::1:8080: Unknown error ! - Android

I am getting this error after updating Android Studio 2.3.2 to Android Studio 3.0 canary 2. Because of this error Internet not working in the emulator.

Edit

I am using Android Studio on Windows 7 over LAN connection.

UPDATE Though, It is not the solution but I downgraded the Android Studio to 2.3.3 and uninstalled the android emulator and reinstalled again. Now it is working fine.

Kindly give more details ..like what type of connection you are using or what is your os. If you are on a proxy network try changing the settings in File -> Settings-> HTTP proxy. If that doesn't work look here

AndroidStudio gradle proxy https://docs.gradle.org/current/userguide/userguide_single.html#sec%3aaccessing_the_web_via_a_proxy

Configuring an HTTP or HTTPS proxy (for downloading dependencies, for example) is done via standard JVM system properties. These properties can be set directly in the build script; for example, setting the HTTP proxy host would be done with System.setProperty('http.proxyHost', 'www.somehost.org'). Alternatively, the properties can be specified in a gradle.properties file, either in the build's root directory or in the Gradle home directory.

Example 12.2. Configuring an HTTP proxy

gradle.properties
systemProp.http.proxyHost=www.somehost.org
systemProp.http.proxyPort=8080
systemProp.http.proxyUser=userid
systemProp.http.proxyPassword=password
systemProp.http.nonProxyHosts=*.nonproxyrepos.com|localhost
There are separate settings for HTTPS.

Example 12.3. Configuring an HTTPS proxy

gradle.properties
systemProp.https.proxyHost=www.somehost.org
systemProp.https.proxyPort=8080
systemProp.https.proxyUser=userid
systemProp.https.proxyPassword=password
systemProp.https.nonProxyHosts=*.nonproxyrepos.com|localhost
