I've already experienced about 5 times (usually once a day) when the API simply stops responding to any requests, and I need to rebuild it to get it working again

Troubleshooting and help

It’s not a problem with the code because it’s running fine on Heroku.

My clients are frequently complaining about the quality of the service.

Hey!

Could you describe the steps to reproduce?

  1. From which region are you testing?
  2. Are you performing other requests at the same time?
  3. Did you check the memory on the instance, it’s one of the common case for requests hanging like this.

I didn’t managed to get a 502 error when testing.
