Canceled auto build frozen and blocking new builds

Cancelled an auto build and even though it’s been more than an hour, the build still says “cancelling” and is represented by a gray bar in the builds section of the repository. No other builds of this repo will go through because of this frozen build. This auto-build is connected to a Bitbucket repository. I’ve found evidence of other people with similar frozen builds, but I haven’t found how anyone has resolved it. Any information would be greatly appreciated!
