MetaboAnalyst not working for LC-MS Spectra!

Hi all,
I am new to MetaboAnalyst. I am trying to run the basic spectrum analysis using the demo dataset that is provided but after half an hour my job gets stuck and on refreshing the page it redirects to troubleshoot page as below. I am experiencing this for last 5 days. I tried with login(my upload itself failed) and also as a guest user the issue did not resolve.
Any help will be really useful
Thank you
