Error 400 when trying to download a file

Hello, 

 

I'm using Dropbox for OTA. It worked for long time up until couple of weeks ago. Now, connection is established, folder list is downloaded, but when trying to download a file, I'm receiving Error 400. Your support team answered similar questions (around Error 400), claiming that the format of the HTTPT request might not be 100% correct.

 

This is an embedded system and I'm using a library of the chip vendor, Texas Instrument (TI), so I do not have access to exact format of the HTTP request. I spoke with TI and they asked for a log from your server that shows the mismatch.

 

Is there a way to get a log from your server that shows the format of the received HTTP request?

 

For a reference, here is the Dropbox HTTP Response:
