Can’t open port 8443 in Windows 10

Solution for Can’t open port 8443 in Windows 10
is Given Below:

I am trying to verify if the client certificate (self-signed) which I generated with openssl is valid. I have created client certificate, client private key, client keystore, and server certificate, server private key, server keystore and server truststore.

I am trying to use the generated server key and certificate in Tomcat by putting the following in server.xml:

<Connector port="8443"
    maxThreads="150"
    scheme="https"
    secure="true"
    SSLEnabled="true"
    truststoreFile="C:New keysServertruststore.jks"
    truststorePass="......"
    keystoreFile="C:New keysServerkeystore_server"
    keystorePass="......."
    clientAuth="true"
    keyAlias="......."
    sslProtocol="TLS"/>  

I have also added client certificate in Google Chrome.

But when I try to visit http://localhost:8443/ I get the error localhost refused to connect.
I added an inbound rule windows firewall to allow port 8443, yet, after doing this, when I test whether the port is open or closed with online tools, it shows that port 8443 is closed.

How do I open this port? Or is there anything else I can do to solve this?
