I have a WordPress multi-site setup on my VPS that has Let's encrypt on it. The main domain (https://zonk.be/) is working without a problem. I have a few sub domains that are mapped to different sites in the same WordPress (via the domain mapping plugin). I have made ServerAlias for all the subdomains (barrio.zonk.be psi36.zonk.be psylo.zonk.be) and ran ./letsencrypt-auto --apache
after relaoding apache2, to make certificates for all. But since psi36.zonk.be for instance, resolves to zonk.be I get a Privacy error in Chrome:
This server could not prove that it is psi36.zonk.be; its security certificate is from www.zonk.be. This may be caused by a misconfiguration or an attacker intercepting your connection.
How could I resolve this?
