# FAQ
#### What IP address does Stockeo use for FTP connections?
Stockeo connects to FTP servers from the IP address **138.197.226.212**. If your supplier's server is protected by a firewall, ask them to whitelist this address so that incoming connections from it are allowed.
#### Metafield that I want to update is grayed out on the metafields list
Stockeo metafields selection list showing available metafields in an automation interface
This usually indicates one of two things: either the metafield is already selected in another automation, or its type is not supported by Stockeo.
For more details, please refer to the [**Supported metafield types**](/data-mapping/metafields.md) section.
#### The automation with the feed hosted on Dropbox doesn't work
A common issue in this case is the URL used in the automation.
By default, the Dropbox share URL redirects to a file preview page embedded in Dropbox. Stockeo requires a direct download link to access the file content.
To fix this, modify the shared Dropbox URL by changing the `dl` parameter at the end of the link from `0` to `1`.
For example:
```
https://www.dropbox.com/scl/fi/7x9k2m1p8qzv0n3a5r8t2/stock.csv?rlkey=123ac456def789&dl=0
```
This URL opens the file in Dropbox preview mode.
To force a direct download, update it to:
```
https://www.dropbox.com/scl/fi/7x9k2m1p8qzv0n3a5r8t2/stock.csv?rlkey=123ac456def789&dl=1
```
This version points directly to the file and allows Stockeo to properly fetch the feed content.
