    I’ve looked through all the forms and the article but couldn’t find anything. It escaped my sight. I would be glad if you help.

    This Wp SMTP plugin also works on subdomain. But it gives an error on the main domain site. How can that be? I am getting an authentication error. Can anyone help?

    Hi @mertsahind,

    Thanks for reaching out!

    It works on the subdomain site with the same settings, only the e-mail addresses are different

    The email address is probably the issue. As per the error message, this user does not have access to the SMTP.

    This user does not have access rights to this service

    You might need to contact your SMTP provider with the SMTP error log.

    First of all, thank you for your reply.

    But there is a problem that we do not understand.

    When we enter the same e-mail address to 8laayt.mertsahindemircioglu.com, all of them are working properly.
    When we enter the main domain name, it does not work, it gives an error.

    When we changed the e-mail addresses, we noticed that while there was no problem in the subdomain web address, there was a problem in the main web site.

    We are getting an error like above.

    I wonder if there was a problem during the wordpress update that we did not notice?

    Such a thing has never happened to us. There is no problem with the e-mail address. When we try this e-mail address on the subdomain site, there is no problem, it works.

    The main website is currently not working e-mail address.
    It works in the subdomain. Very interesting

    Getting the same error. Others are as well. Something is wrong. Can’t connect to host anymore. Says misconfigured SSL but it isn’t. I have checked.

    Misconfigured server certificate.
This means OpenSSL on your server isn't able to verify the host certificate.

There are a few reasons why this is happening. It could be that the host certificate is misconfigured, or this server's OpenSSL is using an outdated CA bundle.

Recommended next steps:
Verify that the host's SSL certificate is valid.
Contact your hosting support, show them the "full Error Log for debugging" below and share this link with them.

    We all may be using Let’s Encrypt for SSL? I just read in another post, it may be the version that is being used by the hosting provider is outdated. Need to upgrade OpenSSL to 1.1.0+ since version is 1.0.2k is now expired. But would also be good to know/verify that it isn’t the plugin having problems.

    Mine is already 1.1.1 anyway. I do not understand.

    How do you say there is a problem (OpenSSL)

    If ssl is a problem, how does the plugin work in subdomail without any problems.
    I think there is a problem when the plugin supports multiple sites. I didn’t know.

    Hi @mertsahind,

    I’ve been looking for answers to this one, but I wasn’t able to find any other instances of this error occurring.

    The Other SMTP mailer can be a little tricky to get working. Have you tried using another mailer from our complete guide to mailers?

    This will likely be the best solution, besides reaching out to your host provider with the error log you initially provided with us.

    Our team will continue looking into the issue.

    Thanks!

    I tried yes. When you said, I tried again, if I did something wrong.. nothing happened. I still get the same error.

    Then I followed these steps..
    1) I uninstalled WordPress with ftp again and installed it clean.
    2) I reinstalled the plugin and tried again.
    3) It was added and I made all the wordpress settings again.

    – The problem still persists. I uploaded my backup files.
    Now my site is working. I’ve seen no problems with any other plugins and other tools. I just observed that this plugin has such problem.
    But the same plugin is installed on the subdomain site. There does not appear to be such a problem.
    We didn’t want to deal with it anymore because of my work. It started to be a waste of time for me. I don’t want to run another team in this. The problem does not appear from our side. Because when you remove the plugin, it sends emails to its own server. But it doesn’t send with the plugin.

    I do not know. If it is fixed with an update, we will wait for it to be resolved. Otherwise we will look at another company with another plugin.

    Hi @mertsahind – I apologize for the confusion. This issue isn’t about the SSL verification. Since the SMTP settings are working on the subdomain, but the SMTP host can’t authenticate you from the root domain, the best approach is to contact your SMTP host with the full error log as the error is thrown by the SMTP server you’re trying to connect to.

    I hope this clarifies!

    I will look at these again. If necessary, I will forward it to other teammates to fix this issue. .
    Let me mark it as completed for now. But I will pass this on to my other teammates. Thank you again.
