Solution: Launch GTA V via Steam or Rockstar Game Launcher, etc.
It will update your game with the latest DLCs.

  • This error is likely because they are using the latest game build for The Contract DLC or whatever it’s called and you haven’t downloaded this in your GTA V game files yet. Simply launch GTA V so it can update. Once done, close it and launch FiveM. You should be good.

I have fixed the issue for some reason if you load up a VPN and connect to America the issues goes away.

Anything else i have tried didnt work.

‘bad record mac’ usually is a sign of a network card passing through corrupted data, some Wi-Fi card vendors somehow have this a lot. Using ‘a VPN’ will usually circumvent this as VPNs have their own error correction/retransmission layer on top, and normal HTTPS apparently does not.
