I never consciously decided to try to use my "synology" certificate for my other domains. I really don't know how that happened. :shock:

I will have do it all again, and this time amend the .htaccess file as well

And this time it worked like a charm

So, in summary:

1. Get a Let's Encrypt certificate for the domain
2. Configure the certificates to use the correct cert for the domain
3. Update Web Station Virtual host to enable https settings
4. Update WordPress > Settings > General to use https://
5. Edit .htaccess to add rewrite conditions
6. Change any internal links on the site that point to http:// pages

Is that correct?

How do I create a Let's Encrypt certificate for a domain and subdomains? Are subdomains included automatically or do i have to list them as alternative names?

Yes your summary is correct. Keep in mind if you create a new website you won’t need to modify .htaccess because the virtual host settings can connect using HTTPS if selected.

It is best to check with the CA vendor when using subdomains as their services vary. For example Let’s Encrypt supports sub domains but some vendors do not.

The Synology knowledge base has good info on creating a CSR for domains and subdomains using DSM.

Regarding adding the HTTPS htaccess entry, this is useful for visitors that may have book marked your site. Browsers store the URL info and switching from http to https or https to http can cause issues. The 301 in the command line let’s browsers know the change you’re making is permanent.

Thanks Steve.

I tried adding my subdomains as SANs on a Let's Encrypt certificate, and it was having none of it. As soon as I removed the SANs the request was granted. Go figure.

It won't accept a separate request for a certificate for a subdomain. Ah well. The subdomains are not that important.

I've never tried adding subdomains to my SSL and I believe most SSL CA vendors charge for that feature.

Free SSL certificates only last 60 to 90 days and since I travel a lot that does not work very well for me. If you forget to renew a certificate, and it expires, users cannot connect to your website.
