Documents API - Azure IP Blocking

Hi,

I’ve been using the API via the Azure Databricks platform to pull information on a number of companies. This has been working fine, in that I am able to get the filing history and profile without any issues.
However, when I use the same authorization to try to get the contents of a specific document, the command runs indefinitely. If I run the same code from my desktop it works without any issue, so it seems to be something firewall-related.
I’ve read other topics suggesting the IP addresses used by Azure may have been blocked in the past. Is there any chance that these are still blocked for “frontend-doc-api.companieshouse.gov.uk”, despite having been unblocked for “api.companieshouse.gov.uk”?
If so, is there any way I can go about getting these unblocked?

Thanks
