Need help with renew LetsEncrypt's cert

Yes if both exists then it's good.

Your system needs 2 seperate ones of these:
/etc/virtual/server.mydomain.com (so your hostname) and
/etc/virtual/mydomain.com (so your domain name)

However, DA shuold indeed not have changed your /etc/virtual/mydomain.com but probably that is not a real bug, but caused because you did not used the correct hostname.

Just to be sure if I were you, I would change the /etc/hosts and /etc/HOSTNAME files too so the correct hostname is in there too.
And reboot the server afterwards.

sorry, I want to confirm about if I change /etc/hosts and /etc/HOSTNAME files I need to change it to server.mydomain.com or mydomain.com?
my hosts file:

123.123.123.123        server.mydomain.com server

my hostname:

server.mydomain.com

and I find my exim(stmp) was changed to server.mydomain.com not mydomain.com too.

Thanks

Yes that is all good now. Hosts file and hostname is good as it is now according to your example. It's also good that the Exim changed to the hostname, that should be hostname too so that is good.

Thank you so much, without your help, I don't know how I finish this.
