Submit page freezes when uploading json results

I am trying to my results.json file (305MB) for the test 2019 GQA challenge, however the Submit page keeps freezing on me and does not upload the file. Here is a screenshot of the page. It never progresses and the results do not show up under “My Submissions”. I was able to upload other results though when the file was smaller (~200MB).

And when I try using the File URL option, that does not work either. It keeps error’ing out that the ‘File does not exists!’ … Even though I have verified with wget that the URL indeed works.

Is there any way I can get evaluation results for this challenge? I’d appreciate any help.
