Network Prerequisites and Regional Troubleshooting for Mainland China Developers Applying for and Calling the Gemini API
Can't call the Gemini API directly from mainland China? This guide covers Google's regional restriction policies, API proxy configuration, and common network handshake interruptions and timeout troubleshooting.
1. Google's Hard Regional Network Restrictions
The Gemini API is currently available in most countries worldwide, but due to policy and compliance restrictions, if a network handshake is initiated directly from mainland China or an unsupported region, the official gateway will cut the TCP connection within milliseconds.
2. Troubleshooting Guidelines for Development and Production Environments
1. Local code debugging environment: Before executing code, make sure the local terminal or IDE has HTTP proxy environment variables configured (e.g., export HTTPS_PROXY=http://127.0.0.1:7890);
2. Cloud server production deployment: Deploy backend services for the production environment on overseas lightweight cloud servers that do not require ICP filing (e.g., US, Japan, or Singapore availability zones), completely eliminating network blocking issues.
