Have had this error for like a year now, all versions... 2026-08-24 00:02:46.969 | HD Request # 3 | Error downloading historical Intraday data for ESU26_FUT_CME. Historical data logon error: Unsupported protocol version Now, the fix... Is simply to turn on ExpressVPN, or Proton VPN, and everything works. I'm still on Windows 10, not 11. |
