Problem in "Submit Project" site

Sir I am trying to upload my project on https://projectsubmission.boltiot.com/
But all the time its same problem

Sir I have already posted the project on hackster.io (http://hackster.io/)
Is this enough or I have to do the same above?

The link for the project submission is not working, because the website seems to be temporarily down.

Please check now. We have fixed the issue and the site is working now. You should be able to submit the project now. Apologies for the inconvenience.
