from the heroku docs on this error code, its saying that this is because the app has not been deployed to git but i have already done so. And when i try to push the code again it returns "everything is up to date".

It looks like you're not waiting until the end of your deployment to make a request.
2018-10-04T01:48:47.400822+00:00 heroku[router]: at=info code=H81 desc="Blank app" method=GET path="/favicon.ico" host=boiling-ocean-24541.herokuapp.com request_id=27da54d0-1040-4eac-b847-897edf10b7ea fwd="184.181.111.193" dyno= connect= service= status=502 bytes= protocol=https
Then, 3 seconds later:
2018-10-04T01:51:50.000000+00:00 app[api]: Build started by user [email protected] 2018-10-04T01:52:25.692316+00:00 app[api]: Deploy 4371d707 by user [email protected]
A few seconds later, we can see the build succeeds:
2018-10-04T01:52:27.000000+00:00 app[api]: Build succeeded
Then app is then started, and 2 requests are made:
2018-10-04T01:52:35.091471+00:00 heroku[router]: at=info method=GET path="/" host=boiling-ocean-24541.herokuapp.com request_id=4ab1f8c2-2d47-4345-bbcd-a370055c0061 fwd="184.181.111.193" dyno=web.1 connect=1ms service=13ms status=404 bytes=415 protocol=https 2018-10-04T01:52:35.271535+00:00 heroku[router]: at=info method=GET path="/favicon.ico" host=boiling-ocean-24541.herokuapp.com request_id=126193f7-90d7-42b4-ad2d-7b52f6e295ca fwd="184.181.111.193" dyno=web.1 connect=0ms service=3ms status=404 bytes=426 protocol=https
No H81 anymore. I don't know what happened on your end, but it appears there were indeed no deploys when you made the first request. The deploy started a few seconds later, and once it was finished, the requests made it through to the app properly.
Solution 2:[2]
Push an empty commit to Heroku to re-trigger the deployment:
git commit --allow-empty -m "Trigger deployment"
git push heroku HEAD:master
You can overwrite this empty deploy on the next push of master:
git push heroku HEAD:master -f

I was facing that annoying error as well, but after running heroku config:set DISABLE_COLLECTSTATIC=1 and then git push heroku HEAD:master it worked!
