Dear customer,
We see that the compression request from the Aspose PSD Compress tool returned a 502 Bad Gateway response:
{"idError":"UnknownError","errorData":"\r\n502 Bad Gateway\r\n\r\n502 Bad Gateway\r\nnginx\r\n\r\n\r\n"}
A 502 status indicates a temporary problem on the server side (the gateway could not receive a valid response from the upstream service). This is not caused by the file itself or by any setting on your end.
What you can try
- Retry the operation after a short wait (a few minutes). The service often recovers automatically.
- Refresh the page and start a new compression request with the same file.
- If the problem persists, clear your browser cache and try again, or use a different browser/network to rule out local caching issues.
- Test with a different PSD file (or a smaller version) to confirm that the issue is not file‑specific.
If the 502 error continues for the same file after several attempts, please let us know:
- The exact PSD file you are trying to compress (or a sample that reproduces the issue).
- The time(s) when the error occurs (including timezone).
With that information we can investigate the backend logs more closely.
We apologize for the inconvenience and appreciate your patience. Please let us know the outcome of the retry or provide the additional details so we can assist further.
