This looks like a duplicate of #106. Can you check what version of requests is installed?

[yufeiluo]

dropbox.Dropbox._API_VERSION
'2'
pip list |grep request
requests (2.14.2)

[yufeiluo]

sudo /usr/bin/pip3.6 install -Iv requests==2.15.1
To test in python3.6,same timeout error.
sudo /usr/bin/pip3.6 uninstall requests
sudo /usr/bin/pip3.6 install -Iv requests==2.16.1
To test in python3.6,same timeout error.
sudo /usr/bin/pip3.6 uninstall requests
sudo /usr/bin/pip3.6 install -Iv requests==2.17.1
To test in python3.6,same timeout error.

I'm experiencing the same for calling dbx.files_upload(). And calling the same method of this ticket's reporter (dbx.users_get_current_account()) breaks it here as well.

Dropbox client version is 8.0.0, the previous I was running (7.3.1) was working fine.

Python 3.5.2

requests==2.13.0
dropbox==8.0.0

[greg-db]

@yufeiluo Apologies, you may actually have to go up to requests v2.18.1. Please try that out.

@dennissiemensma Likewise, please update to requests v2.18.1.

[dennissiemensma]

Thanks, it fixes the problem here! Shouldn't the pip install install this dependency automatically btw?

[greg-db]

@dennissiemensma Thanks for confirming that. And yes, it should. The dependency is listed here. I just tried it, and it did install requests v2.18.1 automatically for me when I ran pip install dropbox. If that didn't work for you, can you share your pip output, if you still have it?

[dennissiemensma]

I see, but I mean.... if 2.18.x fixes the issue, shouldn't be the minimum version be that, instead of 2.5.x (as listed in the setup.py)?
I have added requests==2.18.1 in my own requirements.txt now, so it's fine for me anyway. Just wondering :].

Thanks again for the help, as I can now distribute the update for the dropbox-client v8 for my project.

[greg-db]

I see, thanks for clarifying. Yes, we should probably just raise the requirement in general, since there were several bad requests versions. I'll ask the team to do so. Thanks!

python: 3.5.2
requests: 2.18.4
dropbox: 8.0.0

The problem is still present

[greg-db]

We've updated the dependencies in v8.4.0.

[andreacat]

python: 3.6.1
urllib3: 1.22
requests: 2.18.4
dropbox: 8.7.1

The problem is still present, whether I install urllib3 or not

EDIT: in my case the problem has been solved by upgrading Python from 3.6.1 to 3.6.5
