how to solve "501 Not Implemented" error?

[whaleboss]

When I change wifi network (maybe from home wifi to outside restaurant wifi)
The error is as follows:
INFO: 127.0.0.1:2663 - "GET /start-tunnel?ip=xxx.xxx.xxx.xxx&udid=xxxx-xxxxxxxxx&connection_type=usbmux-tcp HTTP/1.1" 501 Not Implemented
I tried restarting JITStreamer or restarting tailscale or running http://xxx.xxx.xxx.xxx:8080/re but still can't solve it
Is there a way to add the device to the tunnel?
thanks a lot
