RSD not working on Termux?

[xunmod]

I'm trying to use pymobiledevice3 to activate JIT using Termux now. However, I faced a difficult: The tunnel created by pymobiledevice3 can’t be connected.

$ sudo python3 -m pymobiledevice3 lockdown start-tunnel
2025-01-16 22:23:13 localhost pymobiledevice3.cli.remote[6329] INFO tunnel created
Identifier: [UDID]
Interface: tun0
Protocol: TunnelProtocol.TCP
RSD Address: fd09:dbde:8ec9::1
RSD Port: 53521
Use the follow connection option:
--rsd fd09:dbde:8ec9::1 53521

Then the tun0 interface is appeared.

$ sudo ifconfig
tun0: flags=4305<UP,POINTOPOINT,RUNNING,NOARP,MULTICAST>  mtu 16000
        inet6 fd09:dbde:8ec9::2  prefixlen 64  scopeid 0x0<global>
        inet6 fe80::16ff:2a9c:6bbd:c244  prefixlen 64  scopeid 0x20<link>
        unspec 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00  txqueuelen 500  (UNSPEC)
        RX packets 2  bytes 212 (212.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 5  bytes 240 (240.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

However, when I execute python3 -m pymobiledevice3 developer dvt ls /, it was not working:

Where self.address is ('fd09:dbde:8ec9::1', 53521)
I tried to connect to the address given, but it does not connect:

$ telnet fd09:dbde:8ec9::1 53521
Trying fd09:dbde:8ec9::1...
telnet: Unable to connect to remote host: Network is unreachable
$ telnet fd09:dbde:8ec9::2 53521
Trying fd09:dbde:8ec9::2...
telnet: Unable to connect to remote host: Connection refused

What should I check next to figure out the problem and tries to fix it?
