Hi there,

Have you followed a specific tutorial for setting this up?

Usually, to issue a wildcard Let’s Encrypt SSL you would need to have a wildcard DNS entry for your main domain as follows:

*.example.com  A  your_droplet_ip

After that, you could try using the python3-certbot-dns-digitalocean package. You could take a look at the steps on how to complete the rest of the configuration with the DigitalOcean API token here:

Let me know how it goes. Regards, Bobby
