openkaiden/kaiden issue #1875: Ollama v0.2.2 on Windows 11 throws ‘LLM request failed: network connection error’ when trying to communicate with OpenClaw agent. Affects local AI agent setups.
Common causes
- Developers running local LLM agents (like OpenClaw) via Ollama on Windows encounter network connection errors that halt the entire agent loop. This is a common setup issue for local AI development.
- openkaiden/kaiden issue #1875: Ollama v0.2.2 on Windows 11 throws ‘LLM request failed: network connection error’ when trying to communicate with OpenClaw agent. Affects local AI agent setups.
Quick fixes
- Confirm the exact error signature matches
run error: LLM request failed: network connection error. - Check the Ollama account, local tool state, and provider configuration involved in the failing workflow.
- Compare the failing environment with a known working setup, then change one configuration value at a time.
Platform/tool-specific checks
- Verify the command, editor, extension, or API client that produced the error.
- Compare local settings with CI, deployment, or editor-level settings when the error appears in only one environment.
- Avoid deleting credentials, local model data, or project settings until the failing scope is clear.
Step-by-step troubleshooting
- Capture the exact error message and the command, editor action, or request that triggered it.
- Check whether the failure is account/auth, quota/rate, model/provider, local runtime, or deployment configuration.
- Review the source evidence below and compare it with your environment.
- Apply one change at a time and rerun the smallest failing action.
- Keep the working fix documented for the team or deployment environment.
How to prevent it
- Keep provider/tool configuration documented.
- Record non-secret diagnostics such as tool version, provider name, model name, and command path.
- Add a lightweight check before CI or production workflows depend on the tool.

FAQ
What should I check first?
Start with the exact run error: LLM request failed: network connection error text and the smallest action that reproduces it.
Can I ignore this error?
No. Treat it as a failed Ollama workflow until the root cause is understood.
Is this guaranteed to have one fix?
No. The imported evidence supports the troubleshooting path above, but tool behavior can vary by account, plan, version, provider, and local configuration.
How do I know the fix worked?
Rerun the same command, editor action, or request. The fix is working when that action completes without run error: LLM request failed: network connection error.
