Can't open any files from my Android phone

I got a new Android phone about three weeks ago. When I accessed my Dropbox files, I was able to open some and not others. Now I am unable to open any files on the phone. Instead, I receive this message: "This file can't be previewed. To open this file, try a computer or another app." They will not download, export, or be made available offline. However, I can open all the same files on my desktop computer with no problems. I also tried connecting to my Android Dropbox to my desktop Dropbox and starred the item to see if that would help. Still no success. Why can't I open the files on my phone? Thank you for your help.

  • It seems like the device itself isn't allowing the Dropbox app to access the internet to download files. 

    There is a possibility that a proxy, VPN, firewall, security software, or even ISP/router issues could be restricting traffic to the following Dropbox domains.

    I'd recommend checking all of these possibilities, and try connecting to a different WiFi network, or use cellular data, to see if there is any difference.

    Do you have an appropriate application on your phone to open them?

      I have Microsoft Office on my phone, and it opens Word files outside of Dropbox just fine. My phone also opens PDFs outside of Dropbox with no problem. But within the Dropbox app, nothing opens.

      One more thing. On the Dropbox website I can open the same files with my phone that won't open in the app.

    Hi jdt34, let's see what we can find on this! 

    May I ask what OS and Dropbox app are installed on your device? 

    Can you check it and get back to me? 

    Thanks a lot!

        Great. Thanks for the update, jdt34!

        Can you also send us a screenshot of what you see when trying to preview your Microsoft files?

    Can't open .txt files created before by my smartphone of Samsung Note 10.

    Even updated my dropbox but the problem still exists.
    Needed to select account to open the txt files and spent much much time to open.

      Hey Ben, how are you today?

      Do you have an app on your phone that you can use to open them?

      Also, do you get any errors when trying to open them, and if so, can you send us a screenshot? 

      Keep me posted!
