Website not Opening in Chromium based browsers

Hi All,

I have ubuntu 24.04LTS server with hestia cp in a local network with ip starting 10.45.x.x. This server is not connected to internet. Its only meant for local networking for a institution. Few websites are hosted in this. website is meant to load in https mode with Self signed Certificates.

When i use firefox website is loading after accepting the risk of self-signed certificate. everything is fine.

When I use chromium based browsers like google chrome, or edge or brave, i get error “ERR_CONNECTION_REFUSED“ and site is not loading at all.

same site loads with out any issues in firefox.

Anyone knows the issues? I feel its ssl problem. or hts.
