Set `NO_PROXY` for every destination that is not on the public internet, not just model endpoints. The app reaches the realtime server (`SOCKET_SERVER_URL`), the Presidio PII service (`PII_URL`), and itself (`INTERNAL_API_BASE_URL`) over the same default `fetch`, alongside self-hosted Ollama, LiteLLM, and vLLM — so a proxy that cannot reach your internal network breaks live updates and PII redaction, not only inference. AWS clients and OTLP export follow the same rule, so also add an internal S3-compatible store such as MinIO, AWS VPC endpoints, and an in-cluster OpenTelemetry collector.

For the SSRF guard, AWS clients (including the boot-time Secrets Manager fetch), and OTLP export, Sim matches `NO_PROXY` entries the way curl does: `example.com`, `.example.com`, and `*.example.com` each cover the domain and all its subdomains; `host:port` and `[::1]:port` cover one port; IPv6 entries work bare (`::1`) or bracketed; and CIDR ranges such as `10.0.0.0/8` cover IP-literal destinations only, not hostnames that resolve into the range. Bun's default `fetch`, which carries internal service URLs such as the realtime server and PII service, applies Bun's own `NO_PROXY` rules, which may not honor CIDR or bare IPv6 entries, so list those destinations by hostname.

Set it in the application environment, not your shell — under `app.env` on Helm, or the service's `environment:` on Compose. On Helm the suffixes alone are not enough: the chart wires `SOCKET_SERVER_URL`, `PII_URL`, and `OLLAMA_URL` to bare Service names, which no domain suffix matches. Add those names too — `helm template` prints the rendered ones, and the prefix is the release name unless it already contains `sim`, in which case it is the release name alone:
