Most of the home consumer WiFi Routers block inbound connections with no way to unblock them, thus PeerYeet cannot establish a connection. One workaround is to use OpenWRT https://openwrt.org/toh/tp-link/archer_c7 on the router and allow direct connections, but it is not so easy to do.

For example I cannot use PeerYeet on any of my devices, even if I am on the same wifi. So they find the senders, but it is always no direct path, nothing was sent.

Unfortunately you need to relay the traffic.
