Start by reproducing the Gemini request shown in the logs and inspect how the application calls https://generativelanguage.googleapis.com/v1beta/models/gemini-2.5-pro:streamGenerateContent?alt=sse. Determine whether the connection timeout comes from the application configuration or the runtime environment. Done means Gemini requests complete successfully or the issue documents a confirmed external connectivity limitation and an actionable error.
