I want to setup a LetsEncrypt certificate on my delega.app domain. I am hosting using Dokku. However, when I try to use the Dokku plugin it fails and does not offer me any ways to verify without hosting a http:// file on that domain, which is not possible since .app domains do not support un-encrypted HTTP. I tried to self-certify with certbot, which it also does not allow.
For now I’ve set it up with a GoDaddy cert but that is failing in the chain so I’m looking to setup a Let’s Encrypt cert, but not sure how that’s possible if I can’t use DNS or some other method to confirm ownership of domain.
Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My web server is (include version): nginx on dokku
The operating system my web server runs on is (include version): Ubuntu 19.04
My hosting provider, if applicable, is: vultr with Dokku
I can login to a root shell on my machine (yes or no, or I don’t know): yes
I’m using a control panel to manage my site (no, or provide the name and version of the control panel): no
The version of my client is (e.g. output of
certbot --version or
certbot-auto --version if you’re using Certbot): certbot 0.31.0
