License activation failed: Cannot login to JB account from IDE: Broken pipe

Problem

Cannot activate license from Help > Register.. dialog due to the failure to login to the JetBrains account from the IDE. Error message shown: Broken pipe

Cause

Broken pipe error during activation means that the connection between the IDE and our license server has been blocked either by specific security software on the client machine, or somewhere in the network. For example, by a proxy or a VPN.

Resolution

• If using a proxy to connect to the internet, check if the proxy configuration is correct in - Settings (⌘ + , or Ctrl + Alt + S) > Appearance & Behavior > System Settings > HTTP Proxy
• Disable any locally installed antivirus or firewall software.
• Connect to the internet from a different network. For example, using a shared hotspot from a mobile phone
• Activate the license using an offline activation code: https://sales.jetbrains.com/hc/en-gb/articles/360016995379-Activating-JetBrains-IDEs-with-an-offline-activation-code P.S. Some licenses do not support offline activation code (e.g. AI Pro, IDE student/educational pack, etc.).
