TLDR: Do not troubleshoot every TradingView webhook error the same way. A 3xx means the destination redirected the request. A 4xx means the destination rejected it. A 5xx means the receiving server failed. A timeout means the server did not answer within TradingView's three-second limit. URL, TLS, private-IP, refused-connection, and invalid-response errors each point to a different layer. Save the exact message, inspect the matching logs, and make one paper-trading test.

A TradingView webhook is an HTTP POST sent after an alert triggers. The request can fail before it reaches the domain, at a CDN or firewall, inside the application, or after the application calls a broker. The error shown in the Webhook status column is the shortest path to the broken layer.
If maintaining webhook delivery is the recurring problem, UMT Automator offers a browser-based workflow for eligible TradingView strategies without a user-configured webhook, JSON message, broker API key, or custom middleware server. First, use the error itself to understand the current failure safely.
Where Do You Find the TradingView Webhook Error?
Open TradingView's Alerts Log, locate the trigger, and display the Webhook status column. Record:
- Alert name and trigger time.
- Exact error wording and HTTP code.
- Sanitized destination domain and path.
- Whether other alerts to the same endpoint succeeded.
- Matching edge, proxy, application, and broker log entries.
If no alert entry exists, this is not yet a webhook error. The condition did not create an event. If Webhook status succeeded, investigate the receiver and broker instead of resending blindly.
TradingView Webhook Error Code Table
| Error | Meaning | First checks |
|---|---|---|
| 3xx | The endpoint redirected the request. | Final HTTPS URL, changed path, login redirect, proxy rule. |
| 400 | The receiver considered the request invalid. | JSON syntax, required fields, placeholders, schema. |
| 401 | Authentication is missing or invalid. | Current token, secret, authorization design, environment. |
| 403 | The receiver understood but refused access. | WAF, firewall, allowlist, permissions, secret path. |
| 404 | The route was not found. | Domain, path, deployment, capitalization, trailing slash. |
| 429 | The destination rate-limited the request. | Alert burst, receiver limits, queue capacity. |
| 5xx | The receiving service failed to process the request. | Application exception, proxy, queue, database, upstream service. |
| Timeout | No response arrived within three seconds. | Synchronous broker calls, overloaded server, slow network. |
| Invalid URL | The destination cannot be resolved or used. | Typo, DNS, localhost, private IP, inactive domain. |
| TLS error | A secure connection could not be established. | Certificate hostname, expiration, chain, protocol, proxy. |
| Connection refused or closed | The host rejected or terminated the connection. | Listener, firewall, server health, idle timeout. |
| Invalid response | The endpoint returned an unusable HTTP response. | Application and reverse-proxy response handling. |
How Do You Fix 3xx Redirect Errors?
Put the final production endpoint directly into the alert. Redirects commonly come from HTTP-to-HTTPS rules, an old domain, a missing trailing slash, or a gateway that sends unauthenticated traffic to a login page. Test the exact POST route, not only the site's homepage in a browser.
How Do You Fix 4xx Errors?
A 4xx proves that a server received enough of the request to reject it. Compare the response body with receiver logs. Do not rotate every credential at once.
- For 400, validate the final expanded payload and required field types.
- For 401, confirm the authentication value and environment.
- For 403, inspect the WAF, firewall, source rules, and endpoint permissions.
- For 404, copy the current route from the receiver's documentation.
- For 429, reduce bursts or increase safe receiver capacity.
Valid JSON causes TradingView to send application/json. Other messages use text/plain. A receiver that accepts only JSON can reject a message that changed content type after one syntax error.
How Do You Fix 5xx and Timeout Errors?
A 5xx is a receiving-service failure. Inspect logs at the exact trigger time for exceptions, restarts, unavailable dependencies, exhausted connections, or deployment problems.
A timeout has a hard constraint: TradingView cancels the request when the remote server takes longer than three seconds. Authenticate, validate, record an idempotency key, place the event in a durable queue, and respond quickly. Process slower broker work afterward.
TradingView documents resubmission after five seconds for HTTP 500 through 599 responses except 504, with three resends after the original request. One trigger can therefore produce up to four sends. The receiver must prevent duplicate orders.
How Do You Fix URL, TLS, and Connection Errors?
TradingView accepts webhook destination ports 80 and 443 and does not currently support IPv6 targets. Localhost and private network addresses are not public destinations. Confirm that DNS resolves to a reachable public address and that the intended service is listening.
For HTTPS, check the certificate's hostname, expiration, intermediate chain, and proxy configuration. For a refused connection, verify that the service, load balancer, security group, and firewall are active on the public route.
Do Not Confuse Delivery with Trade Execution
A successful HTTP response does not prove the broker accepted or filled an order. A failed response does not prove the receiver performed no work. Track separate states for received, validated, queued, submitted, accepted, rejected, partially filled, and filled.
Before retrying, reconcile the event with receiver and broker records. An uncertain response can hide an order that was submitted before the server failed.
How UMT Removes These Webhook Error Classes
UMT Automator uses an active browser workflow with a TradingView strategy and broker connection inside TradingView. The user does not configure a webhook endpoint, HTTP authentication, JSON schema, or broker API key in UMT. That removes these specific webhook error classes from the user's setup.
UMT still depends on valid strategy activity, the required browser and TradingView tab remaining active, stable internet, and supported broker-side chart trading. Test the complete workflow in paper trading.
The current free 7-day UMT Automator trial can be used to verify strategy detection, account and quantity settings, entries, exits, and operating requirements in paper trading. Review the UMT Automator requirements, follow Getting Started, and request the trial at support@ultramegatrader.com.
Frequently Asked Questions
What does a TradingView webhook error mean?
It means the alert reached the webhook delivery step but the HTTP exchange did not complete normally. The exact code identifies whether the problem is redirection, rejection, server failure, timeout, URL, TLS, or connectivity.
Does a 200 response mean my trade executed?
No. It confirms only a successful HTTP response. Broker submission, acceptance, and fill must be verified separately.
Should I resend a failed trading webhook?
Not until you confirm whether the original event reached the receiver or broker. Resending an uncertain event can create a duplicate order.
Risk and Reliability Notice
Automated trading involves strategy, software, connectivity, broker, and market risk. Webhook delivery and order fills are not guaranteed. Use paper trading, conservative limits, duplicate protection, monitoring, and a manual stop procedure.
