Unable to sync. Which cipher suites are supported by the sync process?

Unable to sync. Which cipher suites are supported by the sync process?

DRSupport
Explorer | Level 3

I noticed the sync process does not work when I restrict the cipher suites to the ones below:


TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384

TLS_DHE_RSA_WITH_AES_256_GCM_SHA384

TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384


According to:


https://www.ssllabs.com/ssltest/analyze.html?d=dropbox.com&s=162.125.248.18&hideResults=on


TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 is supported but for some reason the sync does not complete unless I enable the following cipher suite:

 

TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256

 

Is there a list of supported cipher suites for the sync process?

Hey @DRSupport and welcome aboard to our Community!

 

Just to make sure we are aligned, can I ask if you're using the Dropbox desktop application or an API to complete the process?

 

If you are using the Dropbox desktop application, can you let me know where your Dropbox folder is located, and your app's status

 

If you get any errors don't hesitate to send us a screenshot, and make sure any of your personal information isn't visible when doing so. 

 

Keep me posted with any updates!

Hi Lori,

 

Sorry for my late reply.

 

I installed Dropbox directly on the C drive and when I limit the ciphers used to the ones above the app remains stuck in the sync process. I don't remember the exact wording but I remember it was trying to sync 4 files.

 

Please let me know if you need any more information.

Hey @DRSupport!

Can you try locating your Dropbox icon (on your system tray, next to your WiFi), hover your mouse there and let me know what the status of the application is? 

Also, can you let me know more regarding your process on limiting the ciphers? 

Keep me posted!
