Timeouts with Django channels on dokku

Since I spent hours figuring this out. If you're trying to use django-channels with daphne on dokku and you see any of the following issues:

So do the math if we exclude the outlier (webpack) the average project makes a whopping  $920 per year or about $80/month.  The average US engineer will make that monthly amount in about 1-2 hours. Most of these open source projects I'm sure have several hundred ours of work behind them. It just doesn't make sense. Oh and I forgot to mention t…
