Hello  
I wanted to know if there is a way to run Great Expectations behind a corporate proxy.  
Locally the checkpoint works fine, but when deploying it I receive the following error:  
requests.exceptions.ProxyError: HTTPSConnectionPool(host=‘[stats.greatexpectations.io](http://stats.greatexpectations.io)’, port=443): Max retries exceeded with url: /great\_expectations/v1/usage\_statistics (Caused by ProxyError(‘Cannot connect to proxy.’, OSError( ‘Tunnel connection failed: 407 AuthorizedOnlyYPF’)))

Hello,  
Can someone help me with this problem?

Hi @DJuanes it looks like you have to turn off `anonymous_usage_statistics` --Tthat should be a key in your `great_expectations.yml` that needs to be flipped from `true` to `false`. Please let me know if that works for you!

Thanks for the reply @HaebichanGX  
I set that option to false, but now it shows me another error.  
Running it locally works fine, but not in production environment (Azure Web App)

@DJuanes It’s hard to diagnose without seeing the code. Can you share yours?

Ok. This is the validation function:

def validate\_input() → bool:  
“”"Valida los datos de entrada ejecutando la suite de GE

```
Returns:
    bool: Si los datos son validos o no
"""

data_context: DataContext = DataContext(context_root_dir="./tests/great_expectations")

result: CheckpointResult = data_context.run_checkpoint(
    checkpoint_name="novedades_gidi",
    batch_request=None,
    run_name=None,
)

return result.success

```

Is this a proxy problem or is it something else?

This tool works in production environments or only for development?  
It’s really frustrating.  
Great Deception!!!

Hi there @DJuanes, no GX works for both production and development but it really depends on how you set up GX. It does look like you have a previous implementation of GX, based on looking at your config. But to be sure can you please share your entire code on how you implemented GX end to end?

For more context, we are currently using Fluent Data Source (FDS) which no longer utilizes Data Connectors. Please use this flowchart to visualize the end to end implementation of the new system: [GX Simple Use Case Flow Chart | Lucidspark](https://lucid.app/lucidspark/4373d267-f0bf-4085-8a44-b077277c0748/edit?invitationId=inv_a832619d-4907-4518-b495-2d89c840454f&page=0_0#)
