Various errors while configuring nginx for certificate-based client auth

[lucaprete]

You got it! :)

Some steps before I was using envsubst, which was also trying to substitute
the nginx variables.
Specifying what variables to substitute (i.e. envsubst '$ONLY_THIS_VAR' <
mydomain.com.conf) solved the issue.

Thank you!
