Hello,
We are experiencing consistent 504 Gateway Timeout errors using the Aspose.Diagram Cloud v3.0 REST API. The timeouts occur after exactly 3 minutes (180 seconds).
To isolate the issue, we have performed the following tests:
Sent requests with a dead-simple “Hello World” .vsdx file containing only one rectangle shape to rule out document complexity/corruption.
Attempted conversions to both pdf and png to rule out format-specific engine issues.
Used raw binary streaming (–data-binary) with application/octet-stream to ensure payload integrity.
In all cases, the payload uploads instantly (confirmed by upload completely sent off), but Nginx hangs for 180 seconds before throwing a 504.
Endpoint: PUT /v3.0/diagram/08-174.vsdx/convert?format=pdf
Nginx Response Headers:
HTTP/2 504
x-cluster: cloud-01
x-lb: TLR
Could the engineering team please check if there is an issue or queue backup with the Diagram Cloud rendering worker container on cloud-01? Thank you!
