How to install a certificate from WoSign on Plesk?

Question

JavaScript

Help setting up a certificate on Plesk. There is a site on wp, on plesk (nginx + apache debian server)
I registered and received a certificate for 3 years. It remains only to install it, I did it somehow crookedly and now 80% of browsers write that the connections are untrusted.
On Chrome everything shows correctly, with the latest browsers everything is also in order.
Checked through the service of checks , shows a rating of "B".
(This server's certificate chain is incomplete. Grade capped to B.
This site works only in browsers with SNI support.)
I feel that I set everything up incorrectly, so the question is how to set up a certificate on Plesk?

Answer 1

I have three bananas in my fridge, why isn't the light on?
PS
There is still a tomato, but the light is still not on. With what it can be connected?

Answer 2

So you still need to be able to ask questions ...
Along the way, I remembered a joke:
A lamer approaches a hacker, holds out the source code of his non-working program and asks:
- Where is my mistake?
- In DNA!

Answer 3

Found a solution to this issue.
So you need to use the Folder - for Other Server.
There are two Intermediate files - you need to copy and paste them into the CA-Crt section, and paste the user certificate into the crt section.
Thus, you will get the correct ssl settings for the site on plesk.

Answer 4

If you have not added an intermediate certificate of your certification service, read the instructions from the certificate authority for installing the certificate.
