Hi,
I am using Azure Document Inetelligence URL to analyze a pdf document contains 545 pages (85MB in size) in it. we are using S0 tier configuration to our docment intelligence Service.
So we are able to upload the document but when we try to call to get the analyze Result we have this API as async call , we are verifying the status it shows as running only.. after some time getting the error as An existing connection was forcibly closed by the remote host. So we tried the same from Document Intelligence Studio ,uploaded the same document and It is running from past 2 hours but we are not getting any result.
In fiddler I can see 10 MB is recieved out of 75 MB then server returned error as 504 gateway error.
Could you please help me on this what might be the issue here.

A 504 Gateway Timeout error normally indicates that the server, acting as a gateway or proxy, did not receive a timely response from an upstream server it needed to access to complete the request. This can happen for several reasons, such as:
- Server Overload: The upstream server is overloaded and cannot handle the request in time.
- Server Downtime: The upstream server is down or not functioning properly.
- Network Issues: There might be network connectivity problems between the servers.
- Firewall Issues: Firewalls or other network security measures might be blocking or delaying the request.
Below are suggested solution:
1. Please adjust timeout settings as it may be surpassing the processing limits or timeout settings because 85MB and contains 545 pages long.
2. For Network and Firewall issues, they need to check in firewall or proxy logs and whitelist blocked Azure URLs in their org firewall or proxy side.
3. If virtual network protected, please check network connectivity to private through ping or curl commands and resolve any DNS conflict or missing conditional forwarder etc.
4. you can enable logging for resource setting and check logs in log analytics workspace for detailed analysis including 504 events.
In case you do not see DNS conflict or connectivity issue, you may want to reach out to Azure support for further assistance.
Thank You.

It is working with small size documents.. so I don't see any issue with firewall,or network issues.. I have also tried the same with Azure document intelligence studio.. there also it is taking very long time to process, it took more than 4 hrs but still did not get the json output.
