This indeed sounds fairly similar to what I had experienced.
In our case, we found that the server tended to be more loaded during daytime (in Europe and Africa, that is) and less at night. I’d recommend retrying your download at various times during the day. I had also experimented with different values for the start and limit parameters, but found that they did not have a consistent effect.
I’m adding a link to the download script that we’ve used, for reference. My guess is that it would be relatively easy to adjust that to add retries and the like.
Hi @sanjayadh, based on the time it took for your request, your project may have a large number of submissions in which case @Sjlver is correct, sometimes this can fail based on server load and/or some issues with database efficiency that we’re currently addressing. Likely setting a limit in your URL will solve the issue (but might not as seen here: Cannot export and download my data):
