Fix OpenClaw 401 Errors: Invalid Bearer Token and Missing Auth Header

For an OpenClaw 401, first identify who rejected the request. An invalid provider token, a missing outgoing auth header, and a Gateway or device-token mismatch require different fixes. Check the failing agent and session before replacing credentials.

Fix OpenClaw context_length_exceeded and Failed Compaction

For a large OpenClaw session, save the task state and try supported manual compaction. If the summary request also exceeds its limit, resume in a fresh session from a short record of completed work. Fresh-session failures require checking fixed overhead and the local model's loaded context.

Fix OpenClaw Invalid Beta Flag: Find the Rejected Header and Repair Its Route

Repair an OpenClaw invalid beta flag error by identifying which feature header the selected provider rejected and where it was added. Remove an unsupported optional flag, or repair the required feature's route, then confirm both configuration loading and a completed request.

OpenClaw LLM Setup: Connect Local Models, Cloud Providers, and Fallbacks

Run OpenClaw onboarding on the Gateway host, connect the provider or local server, then select an exact model from its catalog. Verify both a short reply and a harmless tool task. Configured defaults can use fallbacks; a manually pinned chat model remains strict.

Fix OpenClaw 429 Rate Limit Errors: Wait, Recover, or Use a Fallback

When OpenClaw reports a 429, pause extra requests and identify whether the rejection came from the model provider or ClawHub. Wait for a temporary limit, repair exhausted quota or access, and check whether the current selection permits fallback. Preserve completed work before continuing.

Gemini API Paid Tier Getting free_tier_requests Limit 0: What to Fix

A paid Gemini project can still return free_tier_requests limit 0 if the running app uses another project's key, billing setup is incomplete, or the requested model has no usable allowance. Match the request to AI Studio's project, billing status, and active model limits before retrying or replacing keys.

Nano Banana Pro RESOURCE_EXHAUSTED: Fix 429 and Resume Image Jobs

For Nano Banana Pro RESOURCE_EXHAUSTED errors, check the actual project, model, and exhausted limit before retrying. Pause zero allowances, daily limits, and billing blocks; retry transient pressure within a time budget and save confirmed images so a restart does not generate them again.

If OpenAI API auto recharge fails, restore the correct organization's balance, then check the payment attempt, saved settings, and monthly recharge cap. A successful manual top-up restores funds but does not prove automatic recharge is working.
