Heroku problem to upgrade plan

[maxi-89]

Hi everyone. I recently upgraded the redis plan (free to Premium 0) of my staging app on heroku.
with this configuration:

celery==3.1.18
django==2.1.15
djangorestframework==3.9.0
gunicorn==19.8.1
kombu==3.0.37
redis==2.10.3

I am getting this error on sentry:
