I’ve got a Plesk setup which issues Letsencrypt certificates and hosts part of my client websites. When passing the
_achme-challenge and receiving a wildcard certificate / installing said certificate it seems that part of the subdomains which aren’t hosted with me still give a certificate error.
My setup in the DNS is currently as follows:
domain.com– A informational website hosted on my Plesk server.
dev.domain.com– A separate dev site hosted on another IP address eg 123.481.123.12
live.domain.com– Another application entirely, hosted by me and working with the current SSL
As far as I understand this, the other party from
dev.domain.com also needs to install a wildcard certificate on their end? Or is there something wrong with my certificate itself.
