Sierra Chart 2949 (Windows via Wine on a Linux VPS). Service: Rithmic Direct - DTC [trading]. Server: LucidTrading-Chicago Area-Non-Aggregated. Prop firm: Lucid Trading, Rithmic login LT-7TR5V68P, account LFE050-17SF1N5F-TEST001. Every logon returns "Logon error received from server: permission denied" (last at 2026-09-18 10:02 UTC). The same login works in R|Trader Pro (system LucidTrading, Chicago Area) and the Rithmic agreements are signed. Market data / historical username fields are empty. Service Package 10 is active. I sent the Message Log today with "Send For Analysis" (account jbaunez08). Lucid says the account is active and points to Sierra; could you check the log and tell me what is denying the logon, so I can pass it to Lucid?
