Guys,
I’ve tried all you have previously suggested but definitely I cannot succeed with that. Log says that the hostname does not match the server certificate. Any bit of help?
Thanks for your time, it’s bit frustrating.
Cheers!
Fix the server certificate so it matches the hostname. Without knowing which certificate, and which hostname, and how all this came to be, it’s a bit hard to be more helpful than that.
Thanks Matt (@mpalmer)
The complete message from the log is that one:
Sent mail to info@blockchainers.cat (329.6ms)
Job exception: hostname "smtp.blockchainers.cat" does not match the server certificate
And the app.yml file contains as bellow:
## TODO: The domain name this Discourse instance will respond to
DISCOURSE_HOSTNAME: discourse.blockchainers.cat
## Uncomment if you want the container to be started with the same
## hostname (-h option) as specified above (default "$hostname-$config")

I’ve already tried with port 25, 578 and 587. Also modified SiteSetting.notification_email with rails command. No succeed.
Telnet seems to repond well:
root@BLOCKCHAINERS:/var/discourse# telnet smtp.blockchainers.cat 578
Trying 46.16.61.50...
Connected to smtp.blockchainers.cat.
Escape character is '^]'.
220 fnsib-smtp07.srv.cat ESMTP
^]
telnet>
Appart from that, my domain nameserver (CDMON) says that my A register should pint to digitalocean virtual server IP, but my NS should be left empty. It’s a bit confusing to me since Droplet Networking section in digital ocean says I should edit both A and NS registers (please find screenshot attached). . Am I misunderstanding that?
So, I’m running out of ideas to sort it out. Do you have any clue on what is happening or if I’m doing some error with app.yml configuration? By now I can enter the domain and start with Discourse wizard, but no welcome email is entering to my mailbox.
Thanks for all.
Cheers.
That resolves to a single IP address for me (46.16.61.50) and the server there has a certificate for srv.cat and *.srv.cat, not for anything blockchainers. That’s why you are getting the error. On SMTP connection, the banner identifies the machine as fnsib-smtp07.srv.cat, but DNS lookups of that name don’t return that IP address (although it does return six others near by).
(BTW, I checked the cert with https://ssl-tools.net/mailservers in case other people want to test their servers.)
I think you need to get the *.srv.cat name for that mail server.
Thanks @elijah
How can solve that then? My domain nameserver provider says I should not change NS registars, just the A registar. Is that related with your suggestion?
What if I uncomment this line? Should that solve the problem?
## If you added the Lets Encrypt template, uncomment below to get a free SSL certificate
#LETSENCRYPT_ACCOUNT_EMAIL: me@example.com
Cheers.
You should ask whoever you can what DNS name to use for the mail server so that it will agree with the name in the certificate. It’s not your DNS that is at fault, it is the DNS of the mail server.
geting same error … plz help what to do instaled on centos7 with plesk
저도 같은 오류가 발생하는데, 도움을 주실 수 있나요?
메인 서버가 잘못 설정되어 있습니다. 이는 Discourse의 문제가 아닙니다.
메일 서버를 관리하는 담당자에게 연락하여 도움을 요청해야 합니다.
안녕하세요. 여전히 이 문제를 겪고 있습니다…
SMTP 연결은 성공하지만, 그 다음에
Sending mail failed.
hostname "protolife.com" does not match the server certificate
표준 SSL 체크 도구(예: 이것)은 protolife.com 호스트가 인증서를 가지고 있으며, 해당 인증서에 올바르게 포함되어 있다고 보고합니다. 이는 에러 메시지와 모순되지 않나요?
hostname xxx does not match the server certificate 에러 메시지가 어디서 생성되는지 알면 도움이 될 것 같습니다. Discourse에서 생성되는 건가요? SMTP 서버에서 생성되어 discourse.doctor를 통해 전달되는 건가요?
미리 감사드립니다…
