If KuaiLian VPN fails on corporate/campus Wi-Fi, test mobile hotspot; if hotspot works, inspect firewall UDP/port limits and try in-app TCP/alternate protocols; follow IT policy on managed devices.
Same account connects on 5G after work but spins on office Wi-Fi—switching country nodes rarely fixes corporate UDP blocks or DPI. Personal checks: network contrast, protocol swap, document symptoms for IT—don't treat this as MDM removal advice.
Three-step contrast
- Office Wi-Fi vs hotspot: hotspot OK → policy/firewall; both fail → account/client.
- UDP vs TCP protocols: in-app switch per protocol guide.
- Time of day: lunch OK, work hours fail → QoS or proxy schedules.
Managed vs personal devices
MDM laptops may forbid personal VPN. Guides help confirm policy blocks—not replace compliance. Guest Wi-Fi may differ; still follow visitor terms.
