At times, you won’t be able to copy an SSL certificate to services. See below, I cannot copy the SSL certificate to Postfix. On the other hand, the server has 500 domains and they’ve always copied.
The problem is Virtualmin has lost control of the SNI of Postfix and cannot add the entry, mostly likely due to text corruption that throws off the search and replace.
The solution and troubleshooting isn’t straightforward at all.
