OpenSSL - Working in local system but not in other LAN systems [Intranet]

Question

I am using OpenSSL to create SSL certificates to make my web application runnable with https to overcome issues to access microphone in chrome as it stopped allowing access now days without https.

We only need to make it runnable in our Intranet, its not getting live to world.

I used this link to create OpenSSL SSL certificates and configurations.

My V3.ext file contains is as below:

authorityKeyIdentifier=keyid,issuer
basicConstraints=CA:FALSE
keyUsage = digitalSignature, nonRepudiation, keyEncipherment, dataEncipherment
subjectAltName = @alt_names

[alt_names]
DNS.1 = acme-site.dev
DNS.2 = acme-static.dev

Finally its working fine in my local system but not in other systems in our LAN.

enter image description here

I already insert host in that system.

Can anyone help me how to make it runnable in all LAN systems ?

This is a general problem with self-signed certificates. You need to add your self-signed certificated to the list of trusted certificates on all the systems you want to accept it.

If you will be creating more self-signed certificates, you may want to create your own certification authority (CA) and then add its root (or an intermediate) certificate to your systems. There are instructions on setting up a CA at https://jamielinux.com/docs/openssl-certificate-authority/.
