Proposed fix: [nginx in front of LLM backends] Non-streaming or slow-first-token requests fail with 504 after 60 s — proxy_read_timeout default 60s ('upstream timed out')
Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Stream responses (SSE) so bytes flow regularly, have the backend send periodic keepalive/ping events, or raise proxy_read_timeout on the LLM location.
Option: Raise the timeout or keep bytes flowing [evidence: official_recommended_action]
Applies when: See trigger
Steps:
1. location /v1/ { proxy_read_timeout 600s; proxy_pass ...; }
2. or use streaming with periodic ping events
Expected: Error no longer occurs
