its really that easy
refer to your system/software for guides on how to do this (copy and paste "Turn off vpn/proxy firewall" into your browser)









once disabled, it may show the item server connection issue, but thats only until you refresh the game via loading up a match (click play solo or others from the matchmaking menu but you dont have to ready up/play), or closing/reopening the game (loading up solo game menu is faster)

get to this screen and your inventory should have refreshed
note: it may show the issue even after this but check inventory it might be active, the error message is just loitering

note: renabling vpn/proxy will cause you to lose access to the inventory however all equipped skins will remain and display as normal

i would rather use html than use steam for editing a guide this experience sucked
