It looks like the rack_attack gem is throttling your IP. Could you try disabling rack_attack and see if it helps?

Try modifying the below environment variables

## Rack Attack configuration
## To prevent and throttle abusive requests
# ENABLE_RACK_ATTACK=true
# RACK_ATTACK_LIMIT=300
# ENABLE_RACK_ATTACK_WIDGET_API=true
