504 error happening frequently when calling comparison api

When calling the comparison API, I’m seeing the following error happen far too often

Any specific reason why this is happening? Is this because of any rate limits?

@DWHLLC

We are sorry for your inconvenience. We have tested the scenario number of times with sample files, but we are unable to reproduce the reported issue. Please check whether you are facing the issue with some specific file size. We will appreciate it if you please share some sample files here to replicate the issue.

I don’t think its related to file size. Most files are less than 1-2 MB, mostly 6-12 page word documents with no images except, in some cases a company logo on the header. Also, when I retry few minutes later it always works. I run this as a batch job every night and the job spawns 10-15 comparisons almost in parallel. I’m wondering if that is causing some rate limits to be triggered.
