SMTP Error: Could not authenticate.

[Industriutrustning]

Expected Behavior

Send mail from wooCommerce

Current Behavior

Having problem that the plugin wont send mails like password reset. But it will send the plugin test mail. And i get the following error: Email Source: WooCommerce Mailer: Övrig SMTP SMTP Error: Could not authenticate.

I have checked with our webbhost and the test mail shows up but not the basic mails from woo

I am using the latest version of woo, wordpress And WP Mail SMTP

Thanks for the help

Hi @Industriutrustning,

do you have the "Force From Email" checkbox in the WP Mail SMTP settings enabled?

Are you maybe using the PHP constants to configure our plugin?

Do you have any other "email sending/smtp" plugins installed, that could be causing these issues?

Take care!

[Industriutrustning]

Hi Gregor

Thanks for the help.

Regarding your questions:

Force From Email? No I am not using this.

Using the PHP constants?

I am using the following:

define( 'WPMS_ON', true );

define( 'WPMS_SMTP_PASS);

Regarding other plugins the only thing I can think of is that I am using Mailster to send newsletters but I have not changed anything other than upgrading all plugins to the latest.

Thanks again for the help and have a nice day.

Hi Marcus,

do you have your PHP constants set at the end of your wp-config.php file? If you do, please move them above this line: /* That's all, stop editing! Happy publishing. */

That might be the reason why some emails get the "Could not authenticate" error.

Take care!

[Industriutrustning]

Hi Gregor

Ok, I will test this. But I think it is strange that it has worked for over a year previously. And I have not changed anything.

please enable the "Force From Email" checkbox in the WP Mail SMTP plugin and let me know if that resolves it.

Hi Marcus,

could you please remove your PHP constants for our plugin in the wp-config.php file and add the password in the settings page. Just so we can test if that resolves the issue and we know there is something with constants config.

Thanks for trying out all these things. Without direct access, we can't do much but suggest a couple of things to debug.

Take care!

[Industriutrustning]

Hi Gregor

Thanks for the help. That change made it work.

So it looks like something is not working with the constants.

Have a nice day.

Hi Marcus,

it's strange because I tested it with the same use case as you.

I set the constants in wp-config.php, just above the /* That's all, stop editing! Happy publishing. */ line, like so:

define( 'WPMS_ON', true );
define( 'WPMS_SMTP_PASS', 'password_goes_here' );

And I tested the WooCommerce "forgot password" functionality and got the email delivered just fine. I also tested on WooCommerce 5.5.1 and the latest version 5.6.0.

Don't know what it could be. Maybe a plugin conflict? But why only when using constants?

[Industriutrustning]

Hi Gregor

That is a good question, I used the same constants above the That's all line like you and the latest plugins and wordpress the only plugins I can think of that might interfere is Mailster or wordfence

Mailster also connects to a different mail using its own SMPT settings to send newsletters. And wordfence is a security plugin but then it sould not let the test mail function pass. So I don’t know why it wont connect.

Have a nice day

Hi Marcus,

you could try to deactivate the Mailster and Wordfence plugins and try the WooCommerce lost password (with our constants setup). Just to test it out quickly.

Take care!

[Industriutrustning]

Hi Gregor

I tried deactivating the plugins and send again but it did not work. I wounder if it is something with woocommerce but then it should not send other mails.

I activated the constants again and made an order and got the mail. And then tried to send a password request but did not get the mail. So it seems strange.

Thanks for the help.

Hi Marcus,

could you please also try setting these constants:

define( 'WPMS_MAIL_FROM', 'mail@example.com' );
define( 'WPMS_MAIL_FROM_FORCE', true );
define( 'WPMS_SMTP_USER', 'username' );

So, add and define these constants together with the existing WPMS_ON and WPMS_SMTP_PASS.

Let me know how it goes.

[Industriutrustning]

Hi Gregor

Found a guide and added all below and that seems to work.

Thanks again for the help.

define( 'WPMS_ON', true );

define( 'WPMS_MAIL_FROM', '' );

define( 'WPMS_MAIL_FROM_FORCE', true );

define( 'WPMS_MAIL_FROM_NAME', '' );

define( 'WPMS_SMTP_HOST', ' ); // The SMTP mail host.

define( 'WPMS_SMTP_PORT', 465 ); // The SMTP server port number.

define( 'WPMS_SSL', 'ssl' ); // Possible values '', 'ssl', 'tls' - note TLS is not STARTTLS.

define( 'WPMS_SMTP_AUTH', true ); // True turns it on, false turns it off.

define( 'WPMS_SMTP_USER', '' ); // SMTP authentication username, only used if WPMS_SMTP_AUTH is true.

define( 'WPMS_SMTP_PASS', '' ); // SMTP authentication password, only used if WPMS_SMTP_AUTH is true.

define( 'WPMS_SMTP_AUTOTLS', true ); // True turns it on, false turns it off.

define( 'WPMS_MAILER', 'smtp' );

Hi Marcus,

I guess some other values are used for the SMTP Username, when the constant for that field is not used. That's why the "Could not authenticate" error shows up.

Thank you for testing all these different things :)

Have a nice day!
