Bot reject my offer.
I do not know why my shop is now empty and still does not accept the offers and show a notification

Can you try to put in something else? Maybe 1 TF2 item? The error may not be the correct one. Bot probably just cannot accept your trade offer for some reason.

i got same problem, my trade was declined by bot, but bot got my items it shows on my inventory history, so im missing items and on dispenser not showing it
check your inventory history maybe u get answers
