I know it has been a while, but what did your investigation find?
Ha! I was just about to necro bump this thread to query same 😉
I just finally was successfully able to push the 1.10.x NodeBB to Heroku today. But now, every-time it boots it therefore crashes with this crash. The full log from Heroku is below.

I found some information within stackoverflow. That I am going to attempt. StackOverFlow says this: The post is located here:
It looks like a R10 Error Boot Timeout. The error occurs due to the application unable to reach an external resource, like a database. I would double check your DB connection because this error is likely due to an improperly configured database connection. Did you provision a database connection using Heroku's Add-on's? If not, you will have to provision a database to fix the error. mLab is a free option but there are many others. I'll try to walk you through an example of how to do this. Navigate to your Heroku app's dashboard. Click on Resources. In the add-on search box, type in the database service you'd like to provision. If you choose mLab, it will take you to the mLab GUI. Your URI connection string is at the top of the screen. (You want to choose the one labeled "Driver". ) Click on the 'add a user' tab at the center-bottom part of the screen. Add a username and password. Save. After that, copy the URI connection string above, then navigate back to your dashboard. Click on Settings, reveal config vars. Now paste the URI connection string in the text box, then add in your newly created user credentials to replace the <username> and <password> fields. Copy the config variable MONGODB_URI. Next, on your command line, set or export the MONGODB_URI environment variable. Finally, in your application, navigate to where you start your server, then replace the connection to your local host's database with the MONGODB_URI e.g. process.env.MONGODB_URI. Next, Add, commit, push to master then to Heroku. The R10 error should be gone. If it's not, see the links below.
EDIT: This didn't seem to work.
