Persistent HTTP 429 on license key check for several hours despite multiple fixes

What is the issue you’re having?

Hi, I’m setting up a fresh FiveM server (txAdmin, Windows) and I’ve been stuck with the following error for several hours now:

Fatal Error: An error occurred while checking server license key: HTTP 429: 429 Too Many Requests

What I’ve already tried, without success:

Waited 30-60+ minutes with the server fully stopped between attempts
Changed my public IP (router restart)
Changed my DNS to 8.8.8.8 / 8.8.4.4
Generated a brand new server key on Keymaster and updated sv_licenseKey in server.cfg
Fully restarted my PC
Made sure Windows Firewall wasn’t blocking the connection

The server keeps entering a restart loop (txAdmin auto-restarts FXServer after it exits on the 429), which I’ve now manually stopped by killing the process in Task Manager to avoid making things worse.

My current server license key: ■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■

What have you tried already to fix the issue?

  • Waited 30-60+ minutes with the server fully stopped between attempts
  • Changed my public IP address (router restart)
  • Changed DNS to 8.8.8.8 / 8.8.4.4
  • Generated a brand new server key on Keymaster and updated sv_licenseKey
  • Fully restarted my PC
  • Disabled Windows Firewall temporarily to rule it out
  • Manually killed the FXServer.exe process in Task Manager to stop the auto-restart loop caused by txAdmin

What server did you get this issue on?

Local/home server, not yet public - still in initial setup phase (txAdmin fresh install)

Windows version

Windows 11 26200.8875

System specifications

Windows 10, home PC hosting FXServer locally via txAdmin, XAMPP (MySQL/MariaDB) for the database, connecting via port 30120

Antivirus software
