Troubleshooting

Applicable version: technical preview. Never post private keys, authentication tokens, full raw configuration files, production public IPs, private subnets, or unrestricted log dumps to public support channels.

Begin troubleshooting by inspecting local service status, interface ownership (frp-tun:<uid>), policy routing tables (ip rule), and nftables filter counters before checking whether the carrier is toggling between direct P2P and STCP relay modes.

Public issue submissions should only include sanitized version numbers, operating system distribution and architecture, reproducible steps, and categorized error traces.
