Getting lots of connection timeout issues using Python API
The last few weeks I've been getting connection timeout issues more and more often. I am using the Dropbox Python API version 2.2.0 with Python 2.7.11.
For instance, I received this error when downloading a file that is only 473 KB large:
ConnectTimeoutError at /my_company/file/download.pdf (<urllib3.connectionpool.VerifiedHTTPSConnection instance at 0x7f4eaa950950>, ‘Connection to api-content.dropbox.com timed out. (connect timeout=60.0)’)
Here's the code that is being run inside of the view:
response = HttpResponse(content_type='application/pdf')
response['Content-Disposition'] = 'attachment; filename="preview.pdf"'
client = dropbox.client.DropboxClient('my_token')
with client.get_file(path) as f:
response.write(f.read())
return response
Pretty basic stuff. Just downloading the file and rendering it to the response. Yet this resulted in a connection timeout error. Any ideas why?

Hi Grant, thanks for the report. I can't seem to reproduce this here though. About what percent of your API calls are failing?
For reference, I just tried this simplified code, using v2.2.0 of the SDK:
import dropbox
ACCESS_TOKEN = '...'
client = dropbox.client.DropboxClient(ACCESS_TOKEN)
for i in range(100):
print(i)
# /test.pdf is a 4MB PDF file
print len(client.get_file("/test.pdf").read())I didn't get any timeout failures from that. Can you try it too and let me know what you get? Thanks in advance!
Also, there are of course many different factors that can impact network performance and reliability. Can you check on any security software, e.g., anti-virus, firewalls, or proxies that may be impacting your connection? Likewise, are you making many other calls at the same time, or otherwise congesting your network connection? Similarly, your ISP may be having trouble or throttling your connection.
