Heroku deploy stopped syncing

Last week, I deployed an instance of Pontoon to Heroku for an open source project I work on in my spare time. It was syncing fine for a few days, but it has stopped. I currently have some capitalization changes in a couple of fluent string attributes that have been approved, but when I sync, the log tells me that the project is skipped and no new commits are added to the configured branch:
