I have multiple customers reporting that they cannot access the BOX shared links that I send them.  My links are public, accessible to everyone with the link.  Experiation date 30 days, not yet expired.  All of these links work for me just fine, even if I open it on a computer not logged into BOX. 

These companies are all large government contractors with high-security standards.  They’re not going to adjust their settings for me, a lowly sub contractor.

It appears something has changed with BOX that may be triggering their firewalls for the past month.  Can this be resolved?
