Question

SSL certificate failed PLS HELP

As I was trying to add a SSL certificate by running sudo certbot --nginx. It failed to connect to the website. I was using a domain I got from a digital ocean app. I have created an A and AAAA record. Here’s the image of the A/AAAA. PNG IMAGE

Here’s the error I receive while creating the certificate.

Hi there @jadeyongxinli,

There is actually already an SSL certificate for the-new-zombs-io-ploro.ondigitalocean.app. It is covered by the Wildcard SSL certificate for *.ondigitalocean.app.

Can you clarify why do you need another SSL certificate?

Also as a side note, I don’t think that this is would work as in order to use Let’s Encrypt you need to actually be the owner of the domain name, in this case, the *.ondigitalocean.app domain is managed by DigitalOcean and goes through Cloudflare, so Let’s Encrypt will not be able to verify that you own the domain.

Hope that this helps! Regards, Bobby
