Gateway
Trusted proxy auth
When to use
Use trusted-proxy auth mode when:
- You run OpenClaw behind an identity-aware proxy (Pomerium, Caddy + OAuth, nginx + oauth2-proxy, Traefik + forward auth).
- Your proxy handles all authentication and passes user identity via headers.
- You're in a Kubernetes or container environment where the proxy is the only path to the Gateway.
- You're hitting WebSocket
1008 unauthorizederrors because browsers can't pass tokens in WS payloads.
When NOT to use
- If your proxy doesn't authenticate users (just a TLS terminator or load balancer).
- If there's any path to the Gateway that bypasses the proxy (firewall holes, internal network access).
- If you're unsure whether your proxy correctly strips/overwrites forwarded headers.
- If you only need personal single-user access (consider Tailscale Serve + loopback for simpler setup).
How it works
Proxy authenticates the user
Your reverse proxy authenticates users (OAuth, OIDC, SAML, etc.).
Proxy adds an identity header
Proxy adds a header with the authenticated user identity (e.g., x-forwarded-user: [email protected]).
Gateway verifies trusted source
OpenClaw checks that the request came from a trusted proxy IP (configured in gateway.trustedProxies).
Gateway extracts identity
OpenClaw extracts the user identity from the configured header.
Authorize
If everything checks out, the request is authorized.
Control UI pairing behavior
When gateway.auth.mode = "trusted-proxy" is active and the request passes trusted-proxy checks, Control UI WebSocket sessions can connect without device pairing identity.
Implications:
- Pairing is no longer the primary gate for Control UI access in this mode.
- Your reverse proxy auth policy and
allowUsersbecome the effective access control. - Keep gateway ingress locked to trusted proxy IPs only (
gateway.trustedProxies+ firewall).
Configuration
{
gateway: {
// Trusted-proxy auth expects requests from a non-loopback trusted proxy source by default
bind: "lan",
// CRITICAL: Only add your proxy's IP(s) here
trustedProxies: ["10.0.0.1", "172.17.0.1"],
auth: {
mode: "trusted-proxy",
trustedProxy: {
// Header containing authenticated user identity (required)
userHeader: "x-forwarded-user",
// Optional: headers that MUST be present (proxy verification)
requiredHeaders: ["x-forwarded-proto", "x-forwarded-host"],
// Optional: restrict to specific users (empty = allow all)
allowUsers: ["[email protected]", "[email protected]"],
// Optional: allow a same-host loopback proxy after explicit opt-in
allowLoopback: false,
},
},
},
}

TLS termination and HSTS
Use one TLS termination point and apply HSTS there.
Proxy TLS termination (recommended)
When your reverse proxy handles HTTPS for https://control.example.com, set Strict-Transport-Security at the proxy for that domain.
- Good fit for internet-facing deployments.
- Keeps certificate + HTTP hardening policy in one place.
- OpenClaw can stay on loopback HTTP behind the proxy.
Example header value:
Strict-Transport-Security: max-age=31536000; includeSubDomains
Gateway TLS termination
If OpenClaw itself serves HTTPS directly (no TLS-terminating proxy), set:
{
gateway: {
tls: { enabled: true },
http: {
securityHeaders: {
strictTransportSecurity: "max-age=31536000; includeSubDomains",
},
},
},
}
strictTransportSecurity accepts a string header value, or false to disable explicitly.
Rollout guidance
- Start with a short max age first (for example
max-age=300) while validating traffic. - Increase to long-lived values (for example
max-age=31536000) only after confidence is high. - Add
includeSubDomainsonly if every subdomain is HTTPS-ready. - Use preload only if you intentionally meet preload requirements for your full domain set.
- Loopback-only local development does not benefit from HSTS.
Proxy setup examples
Pomerium
Pomerium passes identity in x-pomerium-claim-email (or other claim headers) and a JWT in x-pomerium-jwt-assertion.
{
gateway: {
bind: "lan",
trustedProxies: ["10.0.0.1"], // Pomerium's IP
auth: {
mode: "trusted-proxy",
trustedProxy: {
userHeader: "x-pomerium-claim-email",
requiredHeaders: ["x-pomerium-jwt-assertion"],
},
},
},
}
Pomerium config snippet:
routes:
- from: https://openclaw.example.com
to: http://openclaw-gateway:18789
policy:
- allow:
or:
- email:
is: [email protected]
pass_identity_headers: true
Caddy with OAuth
Caddy with the caddy-security plugin can authenticate users and pass identity headers.
{
gateway: {
bind: "lan",
trustedProxies: ["10.0.0.1"], // Caddy/sidecar proxy IP
auth: {
mode: "trusted-proxy",
trustedProxy: {
userHeader: "x-forwarded-user",
},
},
},
}
Caddyfile snippet:
openclaw.example.com {
authenticate with oauth2_provider
authorize with policy1
reverse_proxy openclaw:18789 {
header_up X-Forwarded-User {http.auth.user.email}
}
}
nginx + oauth2-proxy
oauth2-proxy authenticates users and passes identity in x-auth-request-email.
{
gateway: {
bind: "lan",
trustedProxies: ["10.0.0.1"], // nginx/oauth2-proxy IP
auth: {
mode: "trusted-proxy",
trustedProxy: {
userHeader: "x-auth-request-email",
},
},
},
}
nginx config snippet:
location / {
auth_request /oauth2/auth;
auth_request_set $user $upstream_http_x_auth_request_email;
proxy_pass http://openclaw:18789;
proxy_set_header X-Auth-Request-Email $user;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
}
Traefik with forward auth
{
gateway: {
bind: "lan",
trustedProxies: ["172.17.0.1"], // Traefik container IP
auth: {
mode: "trusted-proxy",
trustedProxy: {
userHeader: "x-forwarded-user",
},
},
},
}
Mixed token configuration
OpenClaw rejects ambiguous configurations where both a gateway.auth.token (or OPENCLAW_GATEWAY_TOKEN) and trusted-proxy mode are active at the same time. Mixed token configs can cause loopback requests to silently authenticate on the wrong auth path.
If you see a mixed_trusted_proxy_token error on startup:
- Remove the shared token when using trusted-proxy mode, or
- Switch
gateway.auth.modeto"token"if you intend token-based auth.
Loopback trusted-proxy identity headers still fail closed: same-host callers are not silently authenticated as proxy users. Internal OpenClaw callers that bypass the proxy may authenticate with gateway.auth.password / OPENCLAW_GATEWAY_PASSWORD instead. Token fallback remains intentionally unsupported in trusted-proxy mode.
Operator scopes header
Trusted-proxy auth is an identity-bearing HTTP mode, so callers may optionally declare operator scopes with x-openclaw-scopes.
Examples:
x-openclaw-scopes: operator.readx-openclaw-scopes: operator.read,operator.writex-openclaw-scopes: operator.admin,operator.write
Behavior:
- When the header is present, OpenClaw honors the declared scope set.
- When the header is present but empty, the request declares no operator scopes.
- When the header is absent, normal identity-bearing HTTP APIs fall back to the standard operator default scope set.
- Gateway-auth plugin HTTP routes are narrower by default: when
x-openclaw-scopesis absent, their runtime scope falls back tooperator.write. - Browser-origin HTTP requests still have to pass
gateway.controlUi.allowedOrigins(or deliberate Host-header fallback mode) even after trusted-proxy auth succeeds.
Practical rule: send x-openclaw-scopes explicitly when you want a trusted-proxy request to be narrower than the defaults, or when a gateway-auth plugin route needs something stronger than write scope.
Security checklist
Before enabling trusted-proxy auth, verify:
- [ ] Proxy is the only path: The Gateway port is firewalled from everything except your proxy.
- [ ] trustedProxies is minimal: Only your actual proxy IPs, not entire subnets.
- [ ] Loopback proxy source is deliberate: trusted-proxy auth fails closed for loopback-source requests unless
gateway.auth.trustedProxy.allowLoopbackis explicitly enabled for a same-host proxy. - [ ] Proxy strips headers: Your proxy overwrites (not appends)
x-forwarded-*headers from clients. - [ ] TLS termination: Your proxy handles TLS; users connect via HTTPS.
- [ ] allowedOrigins is explicit: Non-loopback Control UI uses explicit
gateway.controlUi.allowedOrigins. - [ ] allowUsers is set (recommended): Restrict to known users rather than allowing anyone authenticated.
- [ ] No mixed token config: Do not set both
gateway.auth.tokenandgateway.auth.mode: "trusted-proxy". - [ ] Local password fallback is private: If you configure
gateway.auth.passwordfor internal direct callers, keep the Gateway port firewalled so non-proxy remote clients cannot reach it directly.
Security audit
openclaw security audit will flag trusted-proxy auth with a critical severity finding. This is intentional — it's a reminder that you're delegating security to your proxy setup.
The audit checks for:
- Base
gateway.trusted_proxy_authwarning/critical reminder - Missing
trustedProxiesconfiguration - Missing
userHeaderconfiguration - Empty
allowUsers(allows any authenticated user) - Enabled
allowLoopbackfor same-host proxy sources - Wildcard or missing browser-origin policy on exposed Control UI surfaces
Troubleshooting
trusted_proxy_untrusted_source
The request didn't come from an IP in gateway.trustedProxies. Check:
- Is the proxy IP correct? (Docker container IPs can change.)
- Is there a load balancer in front of your proxy?
- Use
docker inspectorkubectl get pods -o wideto find actual IPs.
trusted_proxy_loopback_source
OpenClaw rejected a loopback-source trusted-proxy request.
Check:
- Is the proxy connecting from
127.0.0.1/::1? - Are you trying to use trusted-proxy auth with a same-host loopback reverse proxy?
Fix:
- Prefer token/password auth for internal same-host clients that do not go through the proxy, or
- Route through a non-loopback trusted proxy address and keep that IP in
gateway.trustedProxies, or - For a deliberate same-host reverse proxy, set
gateway.auth.trustedProxy.allowLoopback = true, keep the loopback address ingateway.trustedProxies, and make sure the proxy strips or overwrites identity headers.
trusted_proxy_user_missing
The user header was empty or missing. Check:
- Is your proxy configured to pass identity headers?
- Is the header name correct? (case-insensitive, but spelling matters)
- Is the user actually authenticated at the proxy?
trusted_proxy_missing_header_*
A required header wasn't present. Check:
- Your proxy configuration for those specific headers.
- Whether headers are being stripped somewhere in the chain.
trusted_proxy_user_not_allowed
The user is authenticated but not in allowUsers. Either add them or remove the allowlist.
trusted_proxy_origin_not_allowed
Trusted-proxy auth succeeded, but the browser Origin header did not pass Control UI origin checks.
Check:
gateway.controlUi.allowedOriginsincludes the exact browser origin.- You are not relying on wildcard origins unless you intentionally want allow-all behavior.
- If you intentionally use Host-header fallback mode,
gateway.controlUi.dangerouslyAllowHostHeaderOriginFallback=trueis set deliberately.
WebSocket still failing
Make sure your proxy:
- Supports WebSocket upgrades (
Upgrade: websocket,Connection: upgrade). - Passes the identity headers on WebSocket upgrade requests (not just HTTP).
- Doesn't have a separate auth path for WebSocket connections.
