Certificate renewing failed and can't send email

My YunoHost server

Hardware: VM in a datacenter
YunoHost version:
I have access to my server: Through SSH
Are you in a special context or did you perform some particular tweaking on your YunoHost instance ?: no

Description of my issue

I have two issues:

  • there is an error when I try to renew my certificate;
  • the command cert-renew can’t send email.

I would like to fix at least the certificate renewing because my certificate is expired.

sudo yunohost domain cert-status mydomain.tld
    CA_type: Let's Encrypt
    summary: CRITICAL
    validity: -4

When I try to renew, there is the error “Error: Certificate renewing for mydomain.tld failed !” without details.

Where can I find the log of this error?
How can I know and configure the recipient of this email? I think I no longer receive email since I changed the main domain name of my yunohost instance (~one year ago).

Thank you in advance!

There’s some more debugging if you upgrade to and/or you can also check the diagnosis interface to see if it’s happy about basic DNS records and web exposure of the corresponding domain

I upgraded Yunohost to with the command below.

sudo yunohost tools upgrade --system

Then I retried to renew the certificate and I had the error:

ERROR The DNS records for domain 'mydomain.tld' is different from this server's IP. Please check the 'DNS records' (basic) category in the diagnosis for more info. If you recently modified your A record, please wait for it to propagate (some DNS propagation checkers are available online). (If you know what you are doing, use '--no-checks' to turn off those checks.)

The IP seems to be good. I will investigate my DNS configuration later. Now I have to go.

Thanks for the help.

I fixed an issue on my DNS records. I deleted IP v6 record (AAAA) and then after the TTL, the certificate renewing works! There is no error but I keep receiving no mail from cert-renew command. Next, I found in /var/log/mail.log the mail “bounced (user unknown)”. I don’t have alias for root@ynh.mydomain.tld. So I added it and I will see if I receive email from cron.
