Plesk Admin Interface and Web Interface Using Different Certificates

We issued a cert for our server with no problem, but when we renewed it, the browsers stop recognizing the certificate and the connection times out.

How do we resolve this problem?

Hi @lightfoot,

You would receive more help if you provide your real domain name, the command/tool used to issue your cert, the command used to renewe it, your web server, if it is a shared hosting or not, if it is Windows, Linux, MacOS, the error message, etc. :wink:

Please, fill these questions:

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g., so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is:

I ran this command:

It produced this output:

My web server is (include version):

The operating system my web server runs on is (include version):

My hosting provider, if applicable, is:

I can login to a root shell on my machine (yes or no, or I don't know):

I'm using a control panel to manage my site (no, or provide the name and version of the control panel):


Hello sahsanu:

Thank you for the quick response:

The domain:

This is the login page for my server - the cert works fine on

I am using the Plesk Onyx (17) admin panel with Centos 6.7

I installed the cert via the panel

Yes I have root access.

Web server is Nginx.

Let me know if you need more information.

Thank you for your time,

you are not using the same certificate

your 8443 binding

your port 443 biding

i can confirm you have multiple certificates issued as well

how and why this is happening and how to fix it is more a question for Plesk support/forums


i have also updated your title so others who may be experienced with plesk or seen a similar problem can help

Hi @lightfoot,

As @ahaw021 comments, you are serving 2 different certificates, the right one on nginx port 443 and the expired one in a service named sw-cp-server on port 8443.

I don’t know what sw-cp-server service does but or you need to restart it or you need to configure it properly to serve your current certificate.

Sorry but I don’t use Plesk so no idea how it works.


Hello Andrei:

Thank you very much for this information-I will contact Plesk support to resolve the problem.


Thank you Sahsanu - I appreciate your help with this problem.
