I can not buy any car at auction

Hi guys!
I am trying to buy back or place a bet but get such a message.
I can sell a car at auction. In the showroom I can buy.
Does anyone know what it is?
blocking or something like that
Today, before this “blocking”, I bought about 50 cars at auction, and maybe because of this? Tell me please.

I don’t think its a limit for winning cars if you bid, but it is a limit(i think 25) if you use the buyout option
