Then I check 'proof.json' file whose size is about 500M

$ du -sh proof.json   
498M	proof.json

After all, I rollback branch to 'jsoares-patch-1'. It works.
proof.json file size is 20K

The size is expected to be larger, as the latest version uses a properly scaled amount of challenges. The servers should accept this data though, and not crash :( Investigating

It looks like the problem has may facets :( Now that I fixed the upload limit size, heroku times out, as it only allows requests to take 30s. Looks like this will be more involved to fix.

Okay, I have enabled gzipping the results when uploading them, and reduced the default challenge count to 200, which makes things pass for me again.
