Summary
A completion request to the OpenRouter API failed due to an HTTP transport error. The model was unable to complete the request, resulting in a failed response from the provider endpoint.
Date/Time
2026-06-22 14:54 EDT
Error Message
HTTP transport error (POST https://openrouter.ai/api/v1/chat/completions):
error sending request for url (https://openrouter.ai/api/v1/chat/completions)
[model=anthropic/claude-sonnet-4.6, provider=openrouter]
Steps to Reproduce
Send a chat completion request via POST to https://openrouter.ai/api/v1/chat/completions.
Specify model anthropic/claude-sonnet-4.6 with provider openrouter.
Observe that the request fails with an HTTP transport error before a response is received.
Expected Behavior
The API should successfully process the POST request and return a valid chat completion response.
Actual Behavior
The request fails at the HTTP transport layer. No completion is returned. The error indicates the request could not be sent to the target URL.
Root Cause (Suspected)
Temporary provider overload or network-level instability on the OpenRouter side. The error occurs at the transport layer before a response is received, suggesting the connection was dropped or refused rather than a malformed request.
Impact
failed to receive no completion output.
Any in-progress agent task is interrupted and fails to "keep going"
Workaround offered by error message
Re-send the request or instruct the agent to "Keep going" to resume from the last known state. The issue is expected to resolve on retry as it is likely transient.
