Cannot Access Shared Folder

Hi ​@S_S123, 

Welcome to Box Community, and we’ll gladly help with your error trying to access a shared folder. 

Let us begin with the following: 

• Do you get this connection error by going to the Box website?
• Is it recurring in all browsers, with incognito or private window included? 
• Is your browser up to date? 
• Restart your machine. 

This error message that you have receive is a common network-related error indicating that the connection between your browser and the server was abruptly interrupted or reset.

You should continue using these additional troubleshooting steps: 

• If you are experiencing this error while trying to access or use Box, you can run a built-in connection test to check the health of your connection:

  • Go directly to https://app.box.com/account/diagnostics or click your profile picture/initials in the upper-right corner of your Box account, select Account Settings, and navigate to the Diagnostics tab.
  • Under the Connection Diagnostics section, click Run Test.
  • Once completed, click Full Report to view or copy the diagnostic details. If the test fails to complete, it is highly likely that a firewall, proxy, or security software is blocking Box domains.

• Since connection resets are frequently caused by network security devices or software blocking traffic, ensure that your firewall, proxy, or antivirus software allows the following essential Box domains:

   
  • *.box.com
  • *.box.net
  • *.boxcdn.net
  • *.boxcloud.com

Hope it helps! Let us know how it goes.
