Question

My Android Studio was working fine till morning, but since tonight I get error saying \"Gradle sync failed: Connection timed out: connect. If you are behind an HTTP proxy, p

Answer 1

Clear proxy setting at gradle.properties (Global properties)

Answer 2

What worked for me was removing the port settings from the Gradle.properties file. I wasn't using any proxy and that resulted in the mismatch. I commented out the following lines

systemProp.https.proxyPort=your_port

systemProp.http.proxyHost=your_proxy

Answer 3

If your Proxy settings is set to No Proxy [Based on how i solved this issue in my case] check out gradle.properties (Global properties) and clear proxy lines.

#systemProp.https.proxyPort=port
#systemProp.http.proxyHost=proxy
org.gradle.jvmargs=-Xmx2048m -XX\:MaxPermSize\=512m -XX\:+HeapDumpOnOutOfMemoryError -Dfile.encoding\=UTF-8 -Djava.net.preferIPv4Stack\=true
org.gradle.daemon=true
#systemProp.https.proxyHost=proxy
org.gradle.configureondemand=false
#systemProp.http.proxyPort=port
android.enableBuildCache=true

For me it was the firewall. Definitely, only that. After adding Android Studio to it's whitelist everything is working like a charm.

Answer 5

I copied a project that was created else where. After removing these proxy credentials:

systemProp.http.proxyPassword=your_password

systemProp.http.proxyHost=host_Ip_address

systemProp.http.proxyUser=your_username

systemProp.http.proxyPort=port_number

in the gradle.properties, it worked like a charm.

Answer 6

If proxy settings are correct then go to file and click on "Invalidate Caches/Restart..." to invalidate the cache and restart android studio.
