App Not Loading

my jira account is:
https://wlcomm.atlassian.net

when i click:
Zephyr Squad -> PLANNING AND EXECUTION -> Cycle Summary
i get:
App is not responding. Wait or cancel?

then eventually:
504 Gateway Time-out

your site at:

says:

All Systems Operational

our testing has grinded to a halt.
Is our account in good standing?
what could be our issue?
