Description


When a selector outbound is used as the detour for a Tailscale endpoint and DNS server,

SFA crashes with nil pointer dereference in Selector.DialContext on the second connection attempt.

First connection works fine — Tailscale connects through the proxy, devices are visible.

Disconnect and reconnect causes crash.

        "final": "proxy"
    }
}


Steps:


    

  1. Import config in SFA
    2. 

  2. Connect — works, Tailscale joins network
    3. 

  3. Disconnect
    4. 

  4. Connect again — crash
    5.

Integrity requirements


    

  •  I confirm that I have read the documentation, understand the meaning of all the configuration items I wrote, and did not pile up seemingly useful options or default values.
    • 

  •  I confirm that I have provided the server and client configuration files and process that can be reproduced locally, instead of a complicated client configuration file that has been stripped of sensitive data.
    • 

  •  I confirm that I have provided the simplest configuration that can be used to reproduce the error I reported, instead of depending on remote servers, TUN, graphical interface clients, or other closed-source software.
    • 

  •  I confirm that I have provided the complete configuration files and logs, rather than just providing parts I think are useful out of confidence in my own intelligence.
