    <description>&lt;P&gt;Thanks for the report! I'm not aware of anything that should be causing this, but we'll be happy to look into this. To help us investigate, please share the following:&lt;/P&gt;
&lt;UL&gt;
&lt;LI&gt;the version number of Python you're using&lt;/LI&gt;
&lt;LI&gt;the version number of the&amp;nbsp;Dropbox Python SDK you're using&lt;/LI&gt;
&lt;LI&gt;an estimate of the percent of these calls that fail&lt;/LI&gt;
&lt;LI&gt;the full error output for a failed call&lt;/LI&gt;
&lt;LI&gt;the output of a &lt;CODE&gt;traceroute&lt;/CODE&gt; or &lt;CODE&gt;tracert&lt;/CODE&gt; to &lt;CODE&gt;content.dropboxapi.com&lt;/CODE&gt; from an affected machine&lt;/LI&gt;

      <title>Frequent Timeouts (&gt;4.5 minutes) during files_upload_session_append_v2</title>

      <description>&lt;P&gt;Hi,&lt;BR /&gt;&lt;BR /&gt;I'm uploading larger files (up to 9.3 GiB) in 4 MiB chunks via the dropbox python library in an Azure function.&lt;BR /&gt;In the last few months they started failing very frequently because on some chunks the&amp;nbsp;files_upload_session_append_v2 times out.&lt;/P&gt;
&lt;P&gt;I increased the timeout to 4.5 minutes, but it still times out.&lt;/P&gt;
&lt;P&gt;Since I'm uploading from an Azure data center I doubt this is an ISP issue.&lt;/P&gt;
&lt;P&gt;Sometimes the chunk gets accepted by dropbox despite the timeout and sometimes not.&lt;BR /&gt;I'm trying to adapt my code for this, but at the same time would like to know if there is any throttling going on or any known issues on the dropbox side.&lt;BR /&gt;&lt;BR /&gt;Thank you!&lt;/P&gt;</description>

      <description>&lt;P&gt;Hi Greg,&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Thanks for replying.&lt;BR /&gt;Python version:&amp;nbsp;3.6.4 (v3.6.4:d48eceb, Dec 19 2017, 06:54:40) [MSC v.1900 64 bit (AMD64)]&lt;BR /&gt;Dropbox SDK version: 8.8.1&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;On the last 2330 calls I got 15 timeouts, so based on this limited data about 0.7% failure rate&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;I'm calling&amp;nbsp;DBX.files_upload_session_append_v2(chunk, cursor) and I'll get a requests Timeout exception on a random chunk during that call.&lt;/P&gt;&lt;P&gt;&lt;BR /&gt;Appaerently&amp;nbsp;Azure web app service intances block ICMP. So I can't use Ping and Tracert, but here is a&amp;nbsp;tcpping result:&lt;/P&gt;&lt;PRE&gt;PS D:\home&amp;gt; tcpping content.dropboxapi.com

      <description>&lt;P&gt;Thanks for following up. Can you share the actual error output though? The particular error type and stack trace may be helpful.&amp;nbsp;Thanks in advance!&amp;nbsp;&lt;/P&gt;</description>
