Sharing Origin Certificate with 2 Hosting / Server


I was wondering if I can reuse my existing Origin Certificate (already used) to another server.
Host_A:Server_A key-cert copied to Host_B:Server_B.

The reason is that DNS (ex. should be used in Host_B:Server_B but the subdomains are already used in Host_A:Server_A and now we are encountering Error 526 on Host_B:Server_B. I suspect the cert sharing is the culprit.

It was working perfectly fine when everything until they’ve decided to do this and nothing pretty much that I can do but to assist the other dev for the configuration and stuffs.

Subdomains in Host_A:Server_A are working.

Also is this IP is from Cloudflare and should redirect to the correct website?

Thank you.
