Zephyr squad cloud not running

We experience, that when we try to open Zephyr squad from JIRA, Zephyr will not open.

We have been in contact with Atlassian, who refers to you as 3. part vendor.

We get this diagram, and it just freezes and never starts up Zephyr.

It goes for all our projects and both for me and other users. It started today August 21.

It is vital for us to get opened again, as all our tests are in Zephyr.
