Can I use the same certificate in a droplet and a load balancer?

I’m setting up load balancing for my website.

I have a droplet which is currently handling (poorly) all of the traffic, so I created a second instance of the backend and setup a LB with SSL passthrough… only to find out I needed client IP’s info, so… I have to switch to SSL Termination.

The thing is, I want this transition to be as smooth as possible, so I decided to have the droplet setup in a way that it can take requests either in stand alone or in load balanced mode.

When setting up the LB in SSL Termination mode it’s asking me to use some certificate.

Inside the options provided I get a list of all my domains so my question is: if I use a certificate that is already being used by another droplet, will that affect the original droplet’s ability to process requests?

That’s a good question. I don’t think that this would be a problem, you should be able to use the same certificate.
