SMTP Error: Could not authenticate.

Thanks, fixes the problem, patch looks good, too.

The patch doesn't fix the issue for me. I applied this patch: smtp_error_could_not_authenticate-3114989-3.patch

In my status report, I still see "SMTP module is enabled, turned on, but SmtpConnect() threw exception SMTP Error: Could not authenticate."

I tried sending a test email with the SMTP module, just to see if the error is a false positive, but the email was not delivered.

@arnolbird Sending a test e-mail worked for me even without the patch. Maybe you have a different problem? Have you double-checked that your credentials are correct?

Can I suggest another change:

Change the lines that set SMTPSecure from:

     $mailer->SMTPSecure == in_array($this->configGet('smtp_protocol'), ['ssl', 'tls']) ? $this->configGet('smtp_protocol') : '';

to:

      $protocol = $this->configGet('smtp_protocol');
      $mailer->SMTPSecure = in_array($protocol, ['ssl', 'tls']) ? $protocol : '';

which is simpler, faster and doesn't exceed the code standard line length.

Applying the patch make the error gone away for me too.

The patch from comment #4 fixed the error in our case too and the module works properly.

Marking Needs Work per comments

Refactored according to #9, which is good for me, avoid calling $this->configGet('smtp_protocol') twice, and setted the third parameter strict of in_array to TRUE. Meanwhile, fixed coding standard violations

Fix test

Hi I got this message as well

SMTP CONNECTION SMTP module is enabled, turned on, but SmtpConnect() threw exception SMTP Error: Could not authenticate.

Drupal 8.8.4 and SMTP Authentication Support 8.x-1.0-beta7

I asked my host provider. All the settings are correct.
And I can also send mails.
Does this have consequences??

In the meantime I was able to get a debug report.
I append it here.

Hi @lomale, applying the patch attached will get the error gone. it does not have serious consequence. Just only show you wrong error info on the status report page even it's correct, nothing more.

Thank you for fixing this!

It would be great to include it in the next release.

#18 patch works for me as well. Marking as RTBC

Patch is not working for Drupal 8.8.3 version. Any help is appreciated

Re:#24 The tests against 8.8.x passed, https://www.drupal.org/pift-ci-job/1617443 and one of my Drupal 8.8.3 instances with this patch appiled works as expected.

patch in #18 seems working for me for one staging and one dev sites.

Module version 8.x-1.0-beta7 Drupal 8.8.3

Patch in #18 worked for me too. Thanks!

Patch in #18 worked for me too. Thanks @jungle

Patch in #18 did NOT solve the problem for me with Drupal 8.8.4. Still the same error message in SMTP module when sending a test email and in watchdog.

#30 I confirm I still have the same problem with 8.8.4. Test email is sent successfully and the error appears on the status report (but no error in the log).

If you see an error like I saw in #6, it can be because of changes at Google (our SMTP provider). In my case, my colleague had to adjust the security settings in the Google account to get things working again. In other words, it was not a Drupal issue in my case.

No, emails are actually NOT sent. I double checked the credentials for authentication and they are correct.

Finally it turned out that an update on the mailserver caused the authentication problem. As this is fixed now, the patch also works for me.

I used #18's patch and it seems to have worked. (drupal 8.8.4)

Hi I come back once more.

I still this message as well

I can send emails.

Can someone give me the exact code I have to write for a correct patch. i.e. #18 or is there a new one.
I'm not very familiar with Terminal commands.
will there be a module update soon.

Thanks Lothar

PS I tested on the Weekend. The mails get out, Functionality is given, but it's an nasty bug with the coming back Errormessage.

When I try to apply the patch in #18 on my dev site I get the following error:

Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - webflo/drupal-core-require-dev 8.8.4 requires behat/mink 1.7.x-dev -> no matching package found.
    - webflo/drupal-core-require-dev 8.8.4 requires behat/mink 1.7.x-dev -> no matching package found.
    - Installation request for webflo/drupal-core-require-dev 8.8.4 -> satisfiable by webflo/drupal-core-require-dev[8.8.4].

I have never had it before on composer updates or installs. Can anyone clarify why it would be happening?

The problem with composer is unrelated to the patch. You should modify your composer.json such that the version constraint on behat/mink is "~1.8", then rerun composer. I had a similar issue which seems to result from mink v1.7 no longer being available.

$ git apply -v 3114989-18.patch

Checking patch tests/src/Unit/ConnectionTester/ConnectionTesterTest.php...

RTBC from here.

#18 3114989-18.patch OK php7.1 D:8.8.5

@ #37: Before adding tags read the issue tag guidelines. Do NOT use tags for adding random keywords or duplicating any other fields. Separate terms with a comma, not a space.

Patches should usually be applied against latest dev to commit to HEAD. Lucky enough latest Beta seems to be the same than latest dev so we need no reroll.

@#18 / #4 while I have confirmed the patches as RTBC already before, I strongly recommend NOT to add cosmetic changes in issues they do not belong to (I have seen some of them in the patches). And at least - IF - then please report them here for tracking them down later. Apart form that +1 for the fixes provided. Code looks good, patch applies on dev also and do not add any harm. Fixes the issue without drawbacks.

I can confirm the patch works fine on 2 production sites too.

+1, please let's get this in. Wasted an hour debugging this alarming status message even though everything is fine.

Yup, looks good to me too. Fixed!

+1!

Thank you

Thanks! :)

Uups it's me
With Drupal Version 8.8.4
i was happy that we had a Update.
SMTP Authentication Support 8.x-1.0-beta7
recommended Version:
8.x-1.0-rc1 (2020-May-08)

I installed it and NEW, I wasn't able to start the status report.
The website encountered an unexpected error, please try later.

i rolled back to beta 7 and the error dissappeared. I have no specific error log messages.
I could show it on 3 other local project's.

I also tried the newest Drupal Version 8.8.5 and both settings on other platforms. Same error.

Just for information.

@lomale : it is likely due to the introduction of the PHPMailer library

see https://www.drupal.org/project/smtp/issues/3135015

Yup, RC2 should help you find your issue here. Which is likely due to missing the PHPMailer library. This issue itself should be fixed though.

YEP rc2 worked also for me.
It show's correctly : missing the PHPMailer library
Thanks

Yes I made it to apply with

composer update drupal/smtp --with-dependencies

the phpmailer library

the error in status report that shows correctly Comment #57 has gone

i ad a picture SMTP Module.png where I found the PHP Mailer
under src in SMTP Module

The sending of the email works, but still an error message. I think nothing critical but anoying.

Hi.
Face off this issue with 8.x-1.0-beta7 and D884.
Is it related to Drupal or/and module version ?

On other website with 8.x-1.0-rc1 + D885 : no message but messages doesn't send.
Test with D885 + rc2 : ?

The test message work in both cases but the D884 display the error message on status report:
SMTP module is enabled, turned on, but SmtpConnect() threw exception SMTP Error: Could not authenticate.
So who say right ? Status report or test message ?

The error disappear after update the module to rc2 + D886:
- Updating drupal/smtp (1.0.0-beta7 => 1.0.0-rc2): Downloading (100%)

Can someone help me here?
