Why Do Colleagues on the Same LAN Fail to Invite Each Other? IP Location and LAN Risk-Control Blocking
Why does an invitation link sent between office colleagues show as invalid? This explains how systems impose anti-abuse restrictions based on the same public egress IP, and offers guidance on compliance assessment and distributing invitations.
1. Corporate Public Egress IP Conflict
In a single office, hundreds of people across the company may appear externally as the same public egress IP address.
If several colleagues place new orders one after another through referral links within a few minutes, the anti-fraud firewall may trigger a risk suspension because of high-frequency closed-loop transactions from the same IP.
2. Compliant Workaround Recommendations
Have invited colleagues use their own independent residential broadband network after returning home from work, or directly turn on a personal 5G hotspot on their phone to register and pay for the first month. This can completely bypass the risk control triggered by overlapping LAN egress.
