[BUG] Port frowarding not working

[PeanTaster]

Describe the bug
If we try to forward the port and access the web server that is on C2, we get a decode error.

To Reproduce
Steps to reproduce the behavior:

1.1.1.1 - C2 host
9.9.9.9 - Compromised host

1. Start proxy

./proxy -selfcert -selfcert-domain tunnels

2. Start web server on port 8000

goshs

3. Start agent

./agent.exe -connect 1.1.1.1:11601 -ignore-cert

4. Set up listener on pivot host

listener_add --addr 9.9.9.9:8000 --to 1.1.1.1:8000
or
listener_add --addr 0.0.0.0:8000 --to 127.0.0.1:8000

5. Try connecting to the web server through a browser or something else

firefox 9.9.9.9:8000

6. See error

[Agent : dom\user@test] » listener_add --addr 9.9.9.9:8000 --to 1.1.1.1:8000
INFO[0872] Listener 0 created on remote agent!
[Agent : dom\user@test] » ERRO[0891] Listener relay failed with error: decode called for unknown payload type: 69  agent="dom\\user@test" listener="[#0] (tcp) [Agent] 9.9.9.9:8000 => [
Proxy] 1.1.1.1:8000"
[Agent : dom\user@test] »

Expected behavior
Can get access to web server without problems

Proxy information:

• OS: Linux kali 6.8.11-amd64
• Architecture amd64
• Version Ligolo-ng 0.7.2-alpha

Agent information:

• OS: Linux kali 6.8.11-amd64, Windows 10
• Architecture amd64
• Version Ligolo-ng 0.7.2-alpha

Can you run with verbosity enabled both on agent and proxy? (-v option)
