When I tried to access the BOX and upload it, it failed.
We believe that the cause is that the network has access restrictions restricted by a firewall.
Since it is not possible to open all sites, I would like to open and upload only specified sites, so please let me know the URL to use when uploading.
Hi 阿部 和成 and welcome to the Box Support Community.
We have a good description about what URLs (yes, there are multiple) to unblock to get Box working behind your firewall: https://support.box.com/hc/en-us/articles/360043696434-Configuring-A-Firewall-For-Box-Applications
