nginx unit + SSL certificates + Alpine Linux == Value doesn't exist

Getting nothing but this:?

{
 "error": "Value doesn't exist."
}

when trying to upload a certificate?

The problem is that your nginx unit was not compiled with SSL support. The error message and logs are singularly un-useful in this respect.

If you install unit-1.21.0-r1 (edge) instead of the default unit-1.17, SSL support is compiled in and you will have a better time.

You're welcome.
