For my case, updating SSL certificate for "mail.mydomain.tld" solved the error.

My client came from another host, so after moving to our server they noticed that everything was fine except existing "SEND AS" or "ALIAS" features via gmail. Since the error "TLS Negotiation failed, the certificate doesn't match the host., code: 0" suggests something about certificates, I noticed that this account was using different certificates from the one running in my server, that being not enough - certificates for "mail.mydomain.tld" was not installed. So I delete the whole certificate and re-installed from my server, and made sure that "mail.mydeomain.tld" has certificate installed. Tested the alias setting and it worked flawlessly. Hope this might help.

Dear Santori,

Thank you for sharing your solution. I tried your solution. However, now I am getting the following error "Oops, we weren't able to finish. Please verify that you have entered the exact settings provided by your other email service. Contact your other email administrator for further details."

Can you please advice on this?

Thank you!

Santeri,

You Sir are a Genius! Thank you so very much!

Everyone what I was doing is pasting the entire link, you just need to post the details in between https:// and :2083/)

What web address do you use for logging into plesk? Is it something like this:

https://docs.plesk.com/en-US/onyx/quick-start-guide/getting-started-with-plesk/understanding-subscriptions.74372/ wrote: You can log in to Plesk by visiting the following URL:
Code: Select all
https://<Plesk server's address>:8443

If it looks something like that, try the <Plesk server's address> as your SMTP server host name in Gmail and see if that works.

GoDaddy "award-winning support team" was again lying to me, so I wasted 24 hours by waiting their "solution" instead of finding the fix by myself right away. Anyway, I found a permanent solution for the issue. It is easy, free and does not involve GoDaddy which means it can be done right away instead of waiting forever for nothing to happen. Here are the steps for fixing Gmail on GoDaddy.

Login to your GoDaddy account

Select All Products and Services

Click Manage in Web hosting section

Click cPanel Admin

Copy host name from cPanel URL (shared server host name is between https:// and :2083/)

Paste the host name to Gmail settings Accounts and Import/Send mail as/edit info/SMTP Server and click Save Changes
What made the issue more complicated was that both gmail and GoDaddy are to be blamed. Gmail has changed how they check SSL certificates and GoDaddy support is exploiting the issue by trying to peddle useless products for their clueless customers. Please let me know if you are still having issues after applying my fix.

Happy hacking,

Santeri

this one doesnt work to me.

Thank you so much, this is the most valuable information I have come across so far better than GoDaddy's service. Unfortunately for me, the problem does not seem to go away. I am getting this after following your steps "Authentication failed. Please check your username/password.
Server returned error: "DNS Error: 9952402 DNS type 'aaaa' lookup of https://sg2plcpnl0131.prod.sin2.secureserver.net:2083/ responded with code NXDOMAIN 9952402 DNS type 'a' lookup of https://sg2plcpnl0131.prod.sin2.secureserver.net:2083/ responded with code NXDOMAIN , code: 0"

Any help will be greatly appreciated thank you
You need to remove ":2083/" from your server address as I mention in my instructions. Try sg2plcpnl0131.prod.sin2.secureserver.net and it should work fine.

THANK YOU SO MUCH! YOU SAVE MYLIFE! I ALREADY FIXED MINE WITH 300+ EMAIL MY GOD!

Can confirm that this works for crazydomains as well.

Hey Owen - are you able to provide instructions to fix the TLS problem with Crazy Domains?

My domain is hosted by godaddy but email is not. This problem started today (18 Apr 2020) and I'm at wits end trying to figure out what to do. I don't even know who to call for support. My domain provider might simply say they have nothing to do with Gmail and google will not even listen. Folks please advise.

I have the same problem but I'm using Hostgator. And I'm not very computer literate when I have to go too deep.

SSL certificates on their server appear to be misconfigured or missing:

If they ever get them fixed, you could try this as SMTP server:

Code: Select all

mail.mt.net.mk

Did you try to follow my instructions? Hostgator is using cPanel just like GoDaddy.

What is your current smtp server name that is not working?

What is the address of your website?

Thank you so much Santeri
I have tryed mail.mt.net.mk but it does not fix it, the only fix is to go with unseccured port 25
