Account switched to 'liquidate only' mode near end of day

[JasonTrades]

Received message on my account near end of day that stated: 'Account switched to liquidate only mode; Total Cash $X, open P/L:$0.00, Day realized P/L: $0.00, Net Liq: $X'
I was not even in a trade today, wondering if this may be due to margin requirements after hours and my account doesn't have enough so they are preemptively switching accounts to liquidate only mode if they don't have the margins for overnight or extended trading. This has me super worried.

Thank you, I sent message to support and found out reason. I had a margin violation that I did not realize.
