Hearthstone Error: "There Was An Error Starting Your Game"
Common ProblemsI receive the error: "There was an error starting your game. Please wait a few minutes and try again."
You can also receive this error while queuing for a game when using an invalid deck. You can solve this problem by deleting the deck then recreating it manually rather than copying a deck code.
In order to play Duels, all classes must be unlocked and levelled to 10.
You will receive this error if you have joined an upcoming Fireside Gathering event that will take place in the future. To resolve this problem, leave the Fireside Gathering: open the Social menu, select the Fireside Gathering event, and then select Leave from the dropdown menu.
You will now be able to play normally. You can join the upcoming Fireside Gathering when the event is meant to take place.
