Understanding the Context

Being blocked by network security means your connection or activity is being restricted by firewall rules, intrusion detection systems, or security policies implemented by your organization (such as a company network) or public internet gateways.

    If your device is infected, your network security system might flag your traffic as high-risk, resulting in a block to protect the network from spreading or receiving harmful data.
