Cert successfully issued (?) via Docker and Nginx but still getting NET::ERR_CERT_AUTHORITY_INVALID and 503

I'm almost wondering if I really need https for both www and non-www since this is only for my backend API?

If I move this all to a subdomain e.g. api.26reads.com , and I make sure all my frontend calls are to the non-www subdomain, would that work?

My frontend would be on Vercel and I'm not sure how relevant this is but they do seem to offer redirect www to non-www and vice versa: Custom Domains – Vercel Docs

I ended up getting rid of Docker for production and using certbot instead of acme-companion.

Much easier! Looks like it's all working now.

Thanks for the help, everyone.
