Every call to api.aspose.cloud/v3.0/diagram/* on our account has been hanging for exactly ~180 seconds before nginx returns a 504 Gateway Time-out. This is reproducible on calls that do zero file processing, so it doesn’t look like a conversion-complexity issue - it looks like the Diagram Cloud backend itself isn’t responding for this account.
We are on the free plan with 0 of 150 calls used this month.
Reproduced independently of our application, straight against the API:
PUT /v3.0/diagram/{name}/convert(actual .vsdx→PDF conversion) — HTTP 504 after 180.2sPUT /v3.0/diagram/storage/file/{name}(raw file upload, no conversion) — HTTP 504 after 180.2sGET /v3.0/diagram/storage/exist/{name}(existence check on a nonexistent file) — HTTP 504 after 180.1sGET /v3.0/diagram/storage/disc(disc-space metadata, no file at all) — HTTP 504 after 180.3sGET /v4.0/words/storage/disc(control — same account, Words Cloud) — HTTP 200 in 741ms
Every Diagram Cloud call fails identically regardless of what it does or whether a file is involved; Words Cloud on the same account/credentials responds normally. This was working previously (last confirmed successful conversion on 2026/05/24 according to API usage logs).
