Gemini Pro 3 - Intermittent Unable to Connect Error

Support Bug Reports
14

Thanks for the detailed testing. The team confirmed the issue based on your data and the Request ID.

This is a known issue with Gemini Pro 3 at high context sizes (around 100 to 120k tokens). The dev team is already working on a fix.

Workarounds:

  • Use Claude 4.5 Sonnet for long tasks, it’s more stable with large contexts
  • Or run /summarize before you reach 100k tokens

We know this is critical for your project given the cost of Gemini 3. The team is working on a fix.
