Hi ​@ishibashi, 

Welcome to Box Community, and we’re glad to help with your Box Drive error.

Before we begin to troubleshoot, we have a few questions related to your error: 

• What is the exact error message shown in Box Drive? It’d be helpful if you could attach a screenshot. 
• Could you check if you’re logged in on the same account in the Box website and Box Drive? 
• What is the Operating System running in your machine?
• What is the Box Drive version?
• Is the error only affecting your shared file or own file, or both?
• Kindly check whether the path/filename might be very long or contain a trailing space or special character. 

We look forward to hear back from you, 

Hi. ​@Rona Box ,

Thank you for your reply.

I have attached a screenshot of the error message.

The answers to my questions are as follows:

- I'm logged in to Box website and Box drive with the same account.

- The operating system is Windows.

- Box drive version is 2.47.174

- I only have shared files, so I don't know if the error occurs with my own files.

-I previously fixed the path/file name and the problem was solved, but since I changed computers, I can no longer access it again.

Actually, I was able to access it five hours after starting work yesterday, but I was unable to access it again this morning.

Thank you in advance.
