I've got a Plesk setup which issues Letsencrypt certificates and hosts part of my client websites. When passing the
_acme-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:
example.com- A informational website hosted on my Plesk server.
dev.example.com- A separate dev site hosted on another IP address eg
live.example.com- Another application entirely, hosted by me and working with the current SSL
As far as I understand this, the other party from
dev.example.com also needs to install a wildcard certificate on their end? Or is there something wrong with my certificate itself.
