Hi Durgesh,

Welcome to the Box Community!

Here are some troubleshooting steps to try:

1. Make sure that the browser is up to date
2. Clear the browsing history or use a different browser
3. Temporary disable plugins/extensions, firewall, and VPN
4. Check if your firewall is configured for Box apps
5. Try to connect to a different network
6. Reach out to the owner of the link and request for a new shared link and make sure the link is set to "people with the link"
 
I trust that the above steps will do the trick. Thank you for posting!
