Installing certificates for Plesk alias domains

Server
1

I have a multisite WordPress setup where each site has its own domain using WPMU DEV’s Domain Mapping plugin. The main site in the network (domainA.com) is setup in Plesk (12.5) as a full website. Each of the sub-sites (domainB.com, domainC.com, domainD.com, etc) are setup as aliases.

I have installed the Let’s Encrypt extension and can create a certificate for domainA.com, however this doesn’t support alias domains. I have also tried Certbot but I think Plesk is causing issues as it complains about vhosts when trying to install the certificates.

Have I missed something or is my setup not currently supported?

Please let me know if you need any additional information. I’d appreciate any advice.

Many thanks,
James

Does anyone have any suggestions? Even an alternative way of doing this would be great.

Many thanks,

looks like the plugin doesn’t support SAN certificates

you can use openssl to create your CSR and then import the cert in to plesk
