Tickets went on sale at 12:01 ET Monday for the first Star Wars standalone film, which hits U.S. cinemas on Dec. 16. Within a few hours online advance ticket seller Fandago crashed, reports Fansided, with customers experiencing long waits on an online queue before receiving a time-out message.

Fandago was aware of the mounting situation early in the evening, telling customers in a tweet that a “wait room” had been created:

Due to an overwhelming amount of traffic, a wait room has been activated. Get #RogueOne tickets soon, you will. https://t.co/Hw6l2LkDYZ pic.twitter.com/4XiYvTMRhT

Fandango’s crash prompted its competitor Atom Tickets to snag disgruntled customers, telling them to head try out their ticketing platform app.

No worries! You can still buy tix AND exclusive gear through the #atomtickets app! #RogueOne
