A co-worker is unable to login to the new Atlassian Cloud GUI. None of my other co-workers (about ten of us) have any problem. He's not a new employee. He browses to "our usual" URL (https://COMPANY.atlassian.net/wiki/, where COMPANY is the name of our instance). He enters his login & return. After a wait, he enters his password and return. After an even longer wait, the page returns with "ERROR The request could not be satisfied ... CloudFront attempted to establish a connection with the origin, but either the attempt failed or the origin closed the connection".
Feels like a time out ... The same thing happens if he tries to login to a browser on my laptop, so it doesn't seem like something specific to his environment. Nothing has changed in his user account.
Suggestions / help appreciated.
