Webmail subbdomain on Namecheap with Acme/LetsEncrypt - HOW?

[ewebgh33]

Hi
Can anyone who uses acme with Namecheap help me figure this out?
I have certificates for domains working with acme.sh and LetsEncrypt.

But Namecheap adds a webmail / mail / cpanel subdomain, for every domain.

I tried adding a certificate for the webmail subdomain. In terminal (via Cpanel) this seems be OK. eg:

acme.sh --issue -d webmail.domain.net -w /home/dir/domain.net
acme.sh --deploy --deploy-hook cpanel_uapi --domain webmail.domain.net

On deploy, it says
Successfully deployed certificate to 0 of 0 sites via UAPI

Why? Why does it not deploy?
Also - I can't seem to add it manually, because in Namecheap's version of Cpanel, you can't install an SLL separately for a subdomain.
This seems dumb, because if I create a subdomain, I have to re-issue the cert for EVERYTHING to cover 1 new subdomain?

ie
Do I instead, have to bundle the subdomains with the main domain.net and www.domain.net, into ONE certificate?
And each time I make a new subdomain (which might happen each week, for example client1.domain.net, client2.domain.net
I have to reissue?

DNS wildcard certs seems risky and problematic... docs mentioned doing this could wipe my records? Don't really want to run that chance.

Did you ever figure this out? I'm facing the same issue. After successfully issuing an SSL Cert, deploying it with the same command results in:

Successfully deployed certificate to 0 of 0 sites via UAPI
