I have a Custom CDN sub-domain with a self created SSL. The SSL has expired.

How can I update the SSL?

I removed the existing sub-domain. I try to create a new one, but, get “must be unique” message. The “old” one (the one that needs a fresh SSL) still appears in the list. When selected, there is no way to update the SSL records.

Thank you.

May I ask what server do you have (OS and etc). You can easily install a Let’s Encrypt SSL using certbot. If you can provide some additional information, I can provide you a step by step guide.


Thanks for the reply.

In April, I created a custom CDN sub-domain with a “Bring your own certificate” in Spaces. The certificate expired in July.

How do I update / renew the CDN sub-domain “Bring your own certificate” without creating a new CDN sub-domain?

From Support:

In order to accomplish what you are aiming at you will need to remove the expired cert from the control panel here:


Keep in mind it won’t let you delete it until you have removed it from your spaces/load balancers. With that complete, you can add a new certificate to the same section with the new certificate, keys etc..

The solution to my own question:

1) I could not remove one of the CDN sub-domains, kept getting an error, but, I was able to remove the sub-domain on another CDN.

2) On the Security tab, the Delete option was still disabled for both CDN sub-domains.

3) On Spaces, I disabled both CDNs.

4) Once the CDNs were Disabled, the Delete option was enabled on the Security tab so I was able to delete the expired SSLs.

Once deleted, I was able to recreate the SSL, turn on CDN and attached the custom sub-domain to the CDN once again. Needless to say, I am going to transfer or register a new domain for my CDN so it is managed by DO so expired LetsEncrypt SSLs are automatically renewed.
