i get "your connection is not private" error on most web browsers like opera, chrome, edge. Some websites are still accessible but others are not.

In Google Chrome and Opera show as: "Your connection is not private" Attackers might be trying to steal your information from domain.com (for example, passwords, messages, or credit cards).

In Mozilla Firefox show as: "Your connection is not secure"

      The owner of domain.com has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website.

In Microsoft Edge show as: "Your connection isn’t private" Attackers might be trying to steal your information from domain.com (for example, passwords, messages, or credit cards).
