In order to unblock access to Google Drive, it is helpful to play around with port settings. The majority of VPN providers allow you to change ports within a few moments, so if you cannot seem to load Google with the default settings, try switching the TCP port 80 to 443. Make sure to restart the app before trying to browse with the VPN again. The firewall reported all the requests to open additional ports after the latest Chrome 26 update. – kingjulien Apr 8 '13 at 10:57 1 If I disable asynchronous dns, remove the new port rules, and then restart Chrome, the firewall no longer requests to open all these additional ports. – kingjulien Apr 8 '13 at 10:59.

I'm using Google drive api V2 to develop an application (server to server), when Ii put this application into my server I have a lot of problems with the firewall rules.

Currently i already enabled the following hosts in my firewall:

Does someone knows the complete list of hosts?

I'm unable to connect the Google Drive application to the Internet. I'm quite sure it's because of the proxy authentication. How can I fix this problem?

Windows 7 64 bit, proxy with authentication.

I'm behind a proxy at work which requires proxy authentication, and wouldn't work with Dropbox. So I followed the instructions in Allow Dropbox to authenticate with an NTLM proxy server to setup Dropbox with Cntlm (a kind of local machine proxy server). Happily you can make Google Drive use the same localhost proxy to connect to the Internet by simply changing your browser settings.

In Internet Explorer: Tools -> Internet Options -> Connections Tab -> LAN settings button.

Set the proxy server address to localhost and the port to whatever you configured Cntlm to use (3128 in my case).

Press OK to the settings and restart Google Drive. So long as your corporate firewall isn't blocking the actual web addresses for Google Drive you should now be OK, and you should still be able to browse.

In fact, Google says: 'Google Drive for Mac/PC supports all unauthenticated proxies that are configured by the operating system.'

I guess this is the same that 'Google Drive for Mac/PC doesn't support authenticated proxies'.

Google has information on what firewall rules to add, but to be honest, compared to Dropbox's simple proxy settings, this one is a pain.

I work in a call center (in IT). We apply a default policy on our proxy so that our callers cannot access the internet (except for select sites) when they are working (they can during their breaks).

As a result anyone in the back office that wants to use the internet for http/s must authenticate with the proxy - which is of cause not supported by Google Drive.

My workaround was to set workstations that need access to Google Drive to bypass the proxy for google.com, which is now allowed through the proxy without authentication.

Application Based Firewalls

I can't see that there is an option for people who have no option but to authenticate with a proxy though.

A crude workaround for online access:

If it's just the file listing that is blocked by the proxy and not the files themselves (like in my company), the following page will list your Google Drive files and allow you to open them:

This is a simple Google app script. It will ask for authorization. You can review the code by replacing exec with edit in the URL:

All you need is just add two keys at your registry. Navigate to the key:

and add String values called ProxyPass and ProxyUser. Fill them with yourProxyPassword and yourProxyUsername and be happy!

If you auth at proxy under domain user, use domainNameusername for ProxyUser key.

Google Drive automatically detects proxy settings.

A workaround is to disable proxy in Internet Explorer and instead to use a proxifier that supports HTTP proxies. You will need to know the network address of the proxy server.

I will use Proxycap in this example. It is easy to configure, and has a very nice option: 'Use integrated Windows authentication'.

Here are the step-by-step instructions:
1. In Proxycap follow these steps:
- Configuration -> Proxies
- Add HTTP proxy (set Type to HTTP)
- Add HTTPS proxy (same settings as for HTTP proxy, but Type=HTTPS)
- Configuration -> Rules
- Add 'Force direct connection' rule for your LAN IP range, such as 192.168.0.0/24
- Add rule: action='redirect', proxy=[HTTP_PROXY], all programs, port=80
- Add rule: action='redirect' proxy=[HTTPS_PROXY], all programs, port=443
- Close the Configuration box by clicking OK.
2. In Internet Explorer follow these steps:
- Tools -> Internet Options -> Connections tab -> LAN settings button
- Uncheck all checkboxes
