Let's Encrypt for sub domains

I have created multiple subdomains(a.example.com, b.example.com etc) and pointed them to different load balancers. How would i be able to provide SSL for all the subdomains and main domain through DigitalOcean’s Let’s Encrypt feature?

Hello, @demonoid92

What you can do is to use a SSL termination which decrypts SSL requests at the load balancer and sends them unencrypted to the backend via the Droplets’ private IP addresses.

Another option is the SSL passthrough, which sends encrypted SSL requests directly to the backend, via the Droplets’ private IP addresses. This secures the traffic between the load balancers and the backend servers.

You can also check our docs on the Load Balancers SSL Termination:

Hope that helps!
