When using Gemini as a translation service in Saladict, translations stop working after a small number of requests (~4–5). After the failure: Translation no longer works Clicking “Test Service” results in failed after 3 attempts No clear error message (rate limit / quota / blocked) The issue recovers automatically after ~5–6 hours without changing any configuration. What has been tested Multiple Gemini API keys New Google AI Studio projects API keys verified to work correctly when tested manually Local Mode (user-provided API key) Cloud Mode (Saladict server) The issue occurs in all cases, including Cloud Mode. Expected behavior Gemini should either: Work consistently, or Return a clear error indicating rate limiting / quota / unsupported usage Actual behavior Gemini silently fails after a few requests Test Service fails Service becomes usable again only after several hours Suspected cause This appears to be server-side throttling or anti-abuse blocking by Gemini, likely triggered by: Dictionary-style short requests High-frequency translation pattern Browser extension / auto-translation use case This blocking seems independent of API key, project, or user IP. Impact The behavior is confusing for users because: The API key appears valid No actionable error is shown The issue resolves automatically after hours, making it hard to diagnose
