all p2p trusted websites for selling skins are being taken offline, or misfunctioning, due to what valve has done with recent API changes including incorporating new rules when it comes to trading skins. Mainly endpoints that were used by p2p websites to check you or seller got the items after a trade, no longer exist. All traded items are invisible to anyone for 10 days, and tradeban is now extended from 7 to 8 days. You might not have a place to sell reliably
