2 ubuntu servers. 1 domain. 1 subdomain. How?

Server
1

Hi, I have created 2 Bitnami-servers through Amazon. I then run through their receipt.

https://docs.bitnami.com/aws/how-to/generate-install-lets-encrypt-ssl/

One domain is mydomain.com and the other is nr2.mydomain.com

Now…the reason I have 2 servers is because the service on one is rented out and I do want it separatly.

The issue is that I cannot get them both to work at the same time. If I register nr2.mydomain.com then mydomain.com stops working and the other way around. How can I with 2 servers have a certificate on one for the domain and the other a certificate for a subdomain?

This needs some more detail:
(What fails to work? and how does it fail?)

This also needs more detail:
(What stops working? Are there any error messages shown?)

This also needs clarification:
(exactly what do you need?)

Yes, I get a message back from Lets encrypt that they do not support subdomains.

Can you post the specific error message? That Let’s Encrypt “[does] not support subdomains” is neither helpful nor an accurate statement. We really need to see the actual message.

One domain is mydomain.com and the other is nr2.mydomain.com

I mean that I can manage to register n22.mydomain.com and get the certificate working, but then mydomain.com stops working - even if I have not touched mydomain.com. So - clearly it has to do with the registretion of the certificate.

If I then change to registering mydomain.com - nr2.mydomain.com stops working (is not safe)

What’s your domain?

Exactly what error message is produced?

This sounds impossible – there is absolutely no conflict between having different servers with different certificates for different hostnames.

Edit:

By the way, Let’s Encrypt has rate limits. Don’t issue too many duplicate certificates from the production environment while working on this.
