Desktops use a wired network, mobile phones use a wireless network, and when restoring WeChat backups, it cannot recognize this as a local area network. I have tested it, and the desktop can normally access the mobile phone’s IP address.

Initially, I thought it was something from Tencent, so I asked “Junhun,” to see if he had any ideas. The results he provided were not helpful. I casually tossed it over to “Dubao,” and he offered a surprise – prompting me to realize that my local environment might have many virtual networks or multi-NIC environments.
This was indeed correct; my desktop has several virtual network cards, such as VMware, ZeroTier, Hyper-V, and Docker Desktop. My desktop also has multiple physical network cards, the primary network card connected to the router and a 2.5G network card forming a sub-local network for another machine.
Therefore, I disabled all virtual network cards and extra physical network cards on my desktop, retaining the primary network card, and reattempted the backup – it was successful!
