If you are sure about the trade offer URL being working, try to re-login to both Steam community and Dispenser.tf.
I and many customer get some "Trade Offer Invalid" when want buy games like in http://dispenser.tf/trade/142705/
it always said my customer trade offer invalid, i try my buyer trade offer too for make sure and that trade offer is valid (work) but when do with bot in that page, it keep said "Trade Offer Invalid". i also try put my trade offer there to make sure, and still said "Trade Offer Invalid"
i use chrome, but i also try do it with internet explorer, and still get same message
i check in develepor tool chrome and get this 404

also in console tab it show
'Attr.nodeValue' is deprecated. Please use 'value' instead.
GET http://dispenser.tf/home/resource/dist/jquery-migrate.min.map; 404 (NOT FOUND)
i dont know if that can help you figure or not. but please fix this bug. i get many buyer who cannot because of that problem.
really weird since other people seem not have problem like me.
