I actually have the link to the auction (got it from the message when I was outbid):

I was on my phone when I tried to place a bid (was using the google chrome).
I don't think that is the case, cuz the auction ended with 24300 fp. Maybe the auction stoped taking bids a few seconds before the timer stoped and instead of the auction is over it showed the not enough fp message? Or maybe the timer on my phone was a bit forward, but usually it let's me click the place bid button before it announces that the auction is over. That's why I thought it was a bit strange
The thing is that it was a matter of seconds so I'm also considering the possibility of being too late
