Hi @tranngocson999,

Which Let's Encrypt client and version are you using on this server? What command do you use to request a certificate renewal?

Hi schoen,
certbot 0.40.0
Command: certbot renew --cert-name mail.shiseidovn.vn

I have two websites on the same server, one is okay, one is not.
I don't know why.

Something may have changed in your Apache configuration since your last renewal.
Please show the output of:
sudo apachectl -S

There is the problem: Each name:port combination used must be unique.
One of those is probably not needed.
Review them, merge them (if needed), and reduce it to just once.

Hi Rudy,
Would you mind telling me how to merge them?

Do you think my problem relates to DNS record?

The "merging" would have to be a completely manual process.
Read and review their separate actions and combine whatever actions are needed into only one vhost config (and remove the other config file).

No.

Hello Rudy,
I'm not sure if this is the solution because I'm not sure what changes I have done so far.
However, I've followed your instructions to make only one vhost config. After that, I've tried again and it works.
You saved my life.
Thank you very much for your help!
