Dropbox Community Moderatorsundares80 I'm not aware of any TLS issues on the Dropbox API servers that should be causing this. We'd be happy to look into it, but we'd need some more specific information. As Здравко said, we'd need to know exactly how to reproduce the issue you're seeing, so please share the specific steps and code to reproduce it.
Also, the output you shared here seems to show some logging specific to the device platform you're using. Can you share any network logging showing the actual TLS issue you're referring to? For instance, a tcpdump showing the issue would be helpful.
Hi Greg,
Thank you both of them for checking this.
Here is the packet capture I got from TI.
This is what I have (the data is encrypted under the TLS):
If the screenshot not clear, Please use the above link.
The Alert is in frame 55151
Please let me know if you have any fix for this.

sundares80 Thanks for sharing that screenshot. Can you share the whole dump though so we can inspect it? Thanks in advance!
Hi Greg,
Please download the wireshark pcap file from below link.

sundares80 We wanted to ask again, since it would be helpful to the team, if you could get and share an unencrypted dump (that is, without the WiFi encryption). The screenshot you shared on 4/24/2024 seems to be of the format we would want to see, but that's not what was shared in the dump you shared the next day (as that one included WiFi encryption). I understand you or your vendor may not want to do so because that would involve effectively sharing the WiFi password, so that could instead be saved and shared as a separate dump, e.g., using the "Export Packet Dissections" "As Plain Text" option, so as not to share the WiFi password.
@Здравко Thank you so much for recreating the issue.
Greg-DB Please find my new packet capture in the google drive link. Please let me know if it works
