I have created a developer edition of a Force.com (Salesforce) as I need to work on poc of a SSO api for work. I changed the domain for the developer edition to alowell-dev-ed.my.salesforce.com (-dev-ed.my.salesforce.com is added by Salesforce as it is a developer edition). I need to create the custom domain so that certs will work in Salesforce.
Part of the setup is that I need a CA-Signed cert. I have created a CA-Signed in Salesforce and downloaded it. But when I run:
sudo certbot certonly --csr dev_cert.csr
An unexpected error occurred:
Error creating new authz :: Policy forbids issuing for name
I imagine that it is because that salesforce.com is blocked? Does that mean it is not possible to use letsencrypt to sign CA-Signed certs for developer editions as they all are a subdomain of my.salesforce.com?
