What this error usually means

NVIDIA returning 404/405 / Base URL mismatch should not be judged from the message alone. Cross-check key shape, Base URL, balance, model permission, region/IP, and visible model list.

  • Provider: NVIDIA
  • Error type: Base URL mismatch
  • Status code: 404/405

How to prove it during checking

Read-only check. Detection data burns after 5 minutes.

  • Run read-only identity first: confirm whether the key really belongs to NVIDIA, not just a compatible protocol.
  • Then list models or run a lightweight probe: check whether models like Llama 3.1 Nemotron 70B Instruct · Llama 3.1 Nemotron Ultra 253B v1 · Llama 3.3 Nemotron Super 49B V1.5 are visible and return stable evidence.
  • Finally record 404/405, error body, latency, egress IP, and reproducibility to separate balance, permission, route, or upstream issues.

Next action

Base URL mismatch should not only show failed. The console should return the next move: refill balance, change Base URL, switch model, add permission, change egress IP, hold listing, or monitor.
