smtp_auth_failed

HTTP status: 502 · Code: smtp_auth_failed

The SMTP server refused the username or password.

Why it happens

The SMTP server refused the username or password.

How to fix

Copy the SMTP credentials again from your email provider. Some providers need an app password or an API key as the password, not your account password.

Catch it in your code

Every SDK throws one error type for a failed call. Match on its code, which is always smtp_auth_failed for this error, never on the message.

JavaScript and Next.js

import { ErrorCode, OrvanoError } from '@orvano/js'

try {
  // your Orvano call
} catch (error) {
  if (error instanceof OrvanoError && error.code === ErrorCode.smtpAuthFailed) {
    // handle smtp_auth_failed
  } else {
    throw error
  }
}

Dart and Flutter

import 'package:orvano_flutter/orvano_flutter.dart'; // or orvano_dart on a server

try {
  // your Orvano call
} on OrvanoException catch (error) {
  if (error.code != ErrorCode.smtpAuthFailed) rethrow;
  // handle smtp_auth_failed
}

.NET

using Orvano;

try
{
    // your Orvano call
}
catch (OrvanoException error) when (error.Code == ErrorCode.SmtpAuthFailed)
{
    // handle smtp_auth_failed
}

The error also carries the HTTP status (502), a message, and a request ID. Quote the request ID when you report a problem: the server logs it with the failure. See Errors for how errors work in every SDK, or every error code.
