# incorrect authentication data – bluehost server

 * Similar to this thread:
    [https://wordpress.org/support/topic/incorrect-authentication-data-error?replies=4](https://wordpress.org/support/topic/incorrect-authentication-data-error?replies=4)
 * When I configure plaintext auth with SMTP with gmail, I get “Incorrect authentication
   data” as the result.
 * I worked with technical support and they verified that the installation is trying
   to authenticate with ‘localhost’ and not the ‘smtp.gmail.com’ so it obviously
   actually IS incorrect authentication data.
 * Interestingly, when I run through the configuration wizard, ‘localhost’ is what
   is populated by default.
 * So, from my eyes, it appears that Postman SMTP is not actually sending the request
   to the configured server “Postman will send mail via 🔐SMTP-STARTTLS to smtp.
   gmail.com:587 using Password (Plain) authentication.”
 * (OAuth does work; but the client does not want to introduce that complexity –
   we can argue if it actually is more complex or not, but not here!)
 * This is an excellent tool, btw. I’ve used WP SMTP for awhile, but dig this more
   for sure!

 * If you run the connectivity test against smtp.gmail.com, do you get a warning
   that is has connected to a different server? What about the wizard did it give
   you a warning as well?
 * Sounds like your Bluehost server is redirecting your connection from gmail to
   your localhost. If that is the case, Postman should be able to detect that it
   hasn’t connected to Gmail.
 * But I don’t see how OAuth 2.0 can work if that is the case.

 * I do get a warning it’s connected to a different server on ports 25, 485 and 
   587 – the servername of the VPS server itself.
 * This is what I think is happening, too…”Sounds like your Bluehost server is redirecting
   your connection from gmail to your localhost.”
 * The API does not have the warning, so that port is not being ‘redirected’ – BlueHost
   was no help in resolving it. Three support cases have all ‘blamed’ the plugin;
   I am convinced it is the server configuration.

 * If you get the warning, then you are being redirected. That’s what the warning
   is for.
 * You won’t get the warning with the API’s because they are not SMTP. It’s a completely
   different port.
 * It’s got nothing to do with OAuth 2.0.
 * Regardless your solution is to connect to your mail.xxx.com server. Bluehost 
   doesn’t allow connections to external SMTP servers.
