Need help activating Let's Encrypt for A record with different IP

Hi! the situation is:
main domain: IP
sudomain: A record IP (it's on a different hosting)

everything works fine, but unfortunately not with SSL :slight_smile: is it possible to do something in this situation? except to have everything with one ip and one hosting

P.S Plesk panel.

Hi @lmz, and welcome to the LE community forum :slight_smile:

Each system can obtain a cert for any FQDN that resolves via global DNS to an IP it controls.

IP can get a cert for that domain.

IP can get a cert for that domain.


Your subdomain on its different hosting should be able to get a certificate there: at its different hosting.


But what if the autossl is not issuing a certificate? there Cpanel

An error occurred the last time AutoSSL ran, on January 10, 2023:
A DNS (Domain Name System) or web server misconfiguration may exist. The domain “” resolved to an IP address “” that does not exist on this server.

but when i ping i see IP :slight_smile: Why Cpanel sees wrong ip? that IP for, but not for

That sounds like two different DNS systems are in use.
DNS should be global and synchronized.
If you care to share some real details, maybe we can unravel this issue.


Beats me, but that's hardly the scope of this Community IMO.


of course two different, because there two different hosting, the main domain has an A record with the ip of another hosting and that's it

main domain: (plesk panel)
subdomain: (cpanel)

two different IP, main domain on plesk has additional A record:, subdomain it has everything by default, I don't understand why on the side cpanel, autossl fail

Maybe the multiple IPs has something to do with it:


Should that be one IP?, or two IPs??

4 Likes seems to be the apex domains IP address.. So any client connecting to the tasks subdomain had a 50 % chance of connecting to the correct IP address of and a 50 % chance of connecting to the incorrect IP address of Doesn't sound correct to me.

Seems to be corrected currently, only a single IP address ( visible for the tasks subdomain at the moment.


Yes, you are right, I did not notice this, this "record A" plesk panel automatically substitutes this entry, thanks for the help, I figured out the error, the topic is closed
