支持 Support

大多数问题都来自同一根 Wi-Fi 线。 Most issues come from one Wi-Fi cable.

对端不出现?Peers don't show up?

• 确认两台设备都连在同一 Wi-Fi。访客网络、隔离 SSID、企业内网常常不可达。Confirm both devices are on the same Wi-Fi. Guest networks, isolated SSIDs, and corporate VLANs often block discovery.
• 路由器若开了"AP 隔离"或"客户端隔离",关闭它。If your router has "AP isolation" or "client isolation" enabled, turn it off.
• iOS 上首次发现需在系统设置中授予本地网络权限。On iOS, grant the Local Network permission the first time you launch the app.
• Windows 上确保 Windows 防火墙允许 transhi.exe 私网入站。On Windows, allow transhi.exe through Windows Firewall for private networks.

配对一直失败?Pairing keeps failing?

• 4 位口令区分大小写,并在 60 秒后过期。请双方同时在场,逐位确认。The 4-character code is case-sensitive and expires after 60 seconds. Confirm digit-by-digit with both devices in hand.
• 如果两台设备时钟差大于 5 分钟,握手可能因证书时间窗口失败。请校时后重试。If the two clocks differ by more than 5 minutes, the handshake can fail due to certificate windows. Sync clocks and retry.

传输到一半中断了?Transfer interrupted?

传世以 1 MiB 分块发送,中断后会自动续传,你不会丢一个分块。如果会话彻底丢失(比如对端关机),重新发送时会从已确认的最后一个分块继续。 Transhi sends in 1 MiB chunks and resumes automatically after a drop. You won't lose a single chunk. If the peer fully goes away, sending again will pick up from the last acknowledged chunk.

Web 访客链接打不开?Web invite link broken?

• 访客必须在同一 Wi-Fi。链接指向你的本地 IP,不在同一网段就不可达。The guest must be on the same Wi-Fi. The link points to your LAN IP — out-of-network means out-of-reach.
• 链接 15 分钟过期,过期后只能再发一条。Links expire after 15 minutes; just issue a new one.
