Docksal Trusting CA Authority

[jjdougherty]

I've been trying to get docksal to use a nonstandard cert per the doc
I've set URL.crt and URL.key in the /etc/certs/custom/ folder and tagged the cert with a label in my docksal.yml

However, when i run fin restart and load the site it still serves the default *.docksal cert.

When I run docker logs docksal-vhost-proxy i get:
[proxyctl notify]: nginx: [emerg] PEM_read_bio_X509_AUX("/etc/certs/custom/URL.crt") failed (SSL: error:0906D06C:PEM routines:PEM_read_bio:no start line:Expecting: TRUSTED CERTIFICATE)

From this i assumed i needed to trust the CA cert to the box. I trusted the cert locally then realized the cert needed to be trusted in the container after i got the same error.

I haven't made much progress on getting the container to trust a CA cert. Has anyone seen anything like this? I didnt know if there was a known fix or if im trying to do something way off base here.
