Title: [Bug] axs reports "Port 8767 already in use" on Node v24.13.0 (Termux)

[TurinFohlen]

Description:
I am encountering a persistent "Port already in use" error when starting the AcodeX server (axs) in Termux. Standard diagnostic tools confirm the port is actually free.
​Environment:
​Node.js Version: v24.13.0 (Experimental/Current)
​Device: Android (Non-rooted, OPPO/Realme build PEHMOO_11_C.24)
​Kernel Version: 5.4.147-qgki-g49f0f78d20a8
​Termux: Latest (F-Droid)
​AcodeX Server: Installed via official script
​Diagnostic Proof:
Despite the error ERROR axs::terminal: Port is already in use, the following commands return no output:
​lsof -i :8767
​netstat -an | grep 8767
​Steps Taken:
​Ran pkill -f axs (No process found).
​Deleted ~/.acodex and cleared $TMPDIR.
​Verified no other apps (like Proot-distro) are using the port.
​Potential Cause:
The issue might be related to Node.js v24.13.0's handling of socket listeners on Android Kernel 5.4.

Update2.14:
I found the root cause and it's quite absurd.

After intense debugging on Termux (Node v24.13.0, Kernel 5.4), I discovered that the Port is already in use error is a false positive generated by the axs startup script's own pre-flight check logic.

​The Proof of Absurdity:

​I performed a "surgical bypass" on the script to prove that the port detection is lying:

The Patch: I forced the script to check port 8888 instead of the default 8767 using sed:

sed -i 's/8767/8888/g' $(which axs)

The Result: The script successfully "verified" that 8888 was free, and then it proceeded to launch the server which successfully bound to the original port 8767.

The Log: INFO axs::terminal: listening on 127.0.0.1:8767

Conclusion:
​The server itself works perfectly. It's the gatekeeper (the startup script) that is broken. It uses a detection method that fails on modern Node/Android environments, reporting EADDRINUSE for a port that is actually vacant.
​To anyone still stuck in 2026 with this issue: Stop looking for hidden processes. Just "trick" the script into checking a different port, and it will let you through.

Node version of axs is deprecated, so use the native version.axs
