HTTP Error 502: Bad Gateway -- when downloading form data

We are currently getting HTTP Error 502: Bad Gateway errors when trying to download form data.

For example:

  • The “DATA” tab in Kobo Toolbox shows an error message.
    https://kobo.humanitarianresponse.info/#/forms/aWjXzx8av32uJaDrnHEj8G/data/report
  • We see a similar error when using the JSON API at https://kobo.humanitarianresponse.info/api/v2/assets/aWjXzx8av32uJaDrnHEj8G/data.json?limit=100&start=0

Both of these methods have worked well before. My last successful download was on November 25. At this time there were 389417 entries. My first failed download was yesterday December 8. The failures are still occurring today.

This might be similar to this recently reported issue: Error message while viewing DATA>Table

We’d appreciate your help. Thanks in advance!
