Hawks fans flocked to Ticketmaster's website Wednesday in hopes of getting free tickets to the team's Stanley Cup celebration at Soldier Field.
Fans reported wait times of up to 45 minutes "due to higher than normal traffic" and many were denied tickets within minutes of them being made available.
Tickets for the rally started popping up on third-party sites like Craigslist shortly after, with some asking for up to $50 per ticket. Several of those posts have since been removed or taken down.
Tickets were also seen posted on eBay with some asking for nearly $500 for four tickets.
Tickets will be needed for the Thursday event at Soldier Field and went live on Ticketmaster.com at 12 p.m. Wednesday.
They were given to fans on a first come first served basis, and individuals were only allowed four tickets each, which would be emailed to print at home.
"The City of Chicago is so proud of the Blackhawks, which is why we are going to throw them a celebration that only Chicago can throw – a celebration worthy of a hockey dynasty," Mayor Rahm Emanuel said in a statement.
