Thanks for the extra info! I did try to follow along out of curiosity and encountered some difficulties on step one. I think that our web interfaces must be different. For me, the URL that you posted in step 1:
https://isles-24.grand-challenge.org/evaluation/preliminary-docker-evaluation/submissions/XXX/
Is close to the URL that I can access by going to the preliminary submission page, where XXX is 'create':
I've tried changing the URL so that XXX is the submission ID of by failed submission, but I get an error saying that the content does not exist. When I navigate to the failed submission using the UI (clicking the 'your submissions' tab, I end up at a different URL: https://isles-24.grand-challenge.org/evaluation/submissions/
I cannot find a link or section titled 'evaluation' and, although there is a link to a results page for my successful submissions, such a link does not exist for any that have failed. My colleague is struggling with a similar issue, but I worry that I have just missed an obvious hyperlink similar to how you had to help me find the 'create an algorithm' page. :)
Thanks,
Anthony
