cannot connect to https://www.tensorflow.org/

[shartoo]

hi, i cannot connect to the home site of tensorflow for long. Can you fix this? My location is China, i can visit Google , tweet,facebook and so on,but no access to tensorflow ,Neither can my friends do.

[tobegit3hub]

Not really an issue. I can access https://www.tensorflow.org/ in China.

You should check your host file or configuration of proxy.

[shartoo]

When i ping www.tensorflow.org ,it responses like below

 Ping ghs-migration.l.google.com [74.125.203.214]
.....
losss 100%

Sounds like a routing problem rather than an issue with The Great Firewall. Have you tried restarting both your computer and router?

[shartoo]

Yes, this problem last for about two months .during this period ,i have never gotten access to www.tensorflow.org.

[hholst80]

What is the result from a traceroute from your computer to www.tensorflow.org?

[shartoo]

Here is the output of my routing:

I am not an expert but it looks like your traffic is still left in mainland China (your Ping time should be much higher also as www.tensorflow.org is hosted in the USA). Contact either your ISP or CHINANET.

it is caused by great firewall. however, It is not totally blocked and I can visit it occasionally. I suggest you to use vpn or proxy.

I don't understand why did it try to visit ghs-migration.l.google.com first. To bypass the GFW, i changed my hosts file,there are many name to ip map,but no item about tensorflow.

[hholst80]

Wait what? Tracing route to 11.1.0.1? That resolves to DoD. I can understand if traffic to the Department of Defense (in the USA) is blocked by GFW. The name resolver seems to be random. Maybe it is a GFW issue anyway. In any case its not a bug in tensorflow.org. :-)

[shartoo]

It's ghs-migration.l.google.com [74.125.204.214] not 11.1.0.1 ,to transfer the content to english, i copy sth wrong from other site.
All right ,it's not a bug of tensorflow, but sth annoying , some of my friends get the same problem.

[shartoo]

It seems www.tensorflow.org had been blocked by GFW. I can't understand the logic behind this!

[yaroslavvb]

I'm guessing the problem is that tensorflow.org resolves to "
ghs-migration.l.google.com" and google.com domains are blocked

Unfortunately this might not be something we can easily resolve. Community contribution welcome. :)

[shartoo]

add this to the hosts file,can fix this.

#TensorFlow start
64.233.188.121  www.tensorflow.org
#TensorFlow end

[eecrazy]

great, thanks to @shartoo

[Helloworld050664]

your IP address is on tensorflow's server blacklist go to

http://www.ipvoid.com

[youngxiao]

Thanks for your answer, @shartoo. It really works. By the way, I'am Chinese too.

[chengshuyi]

@shartoo I type 64.233.188.121 in browser,but it cant be accessed.Does that way you supposed still could work or not?

[ghost]

thanks to @shartoo , it's worked.

[wxwang0601]

that's really helpful, thanks to @shartoo

[Guitarja]

@chengshuyi Yes, it does.

[SiriusHsh]

@fangpin Yes,I also found this question, how do you solve the problem？

[fangpin]

@SiriusHsh I fount it's the VPN settings problem which cause this situation. For example, I use shadowsocks on mac, it will be all ok when I use the global mode instead of auto mode. So maybe it works for you too. By the way, I use shadowsocks and chrome with extension swithchyomega on ubuntu.

[gchen2101]

it works, thanks to @shartoo

[SiriusHsh]

amazing, when I use the global mode instead of auto mode, it shows the correct page. I also use shadowsocks and Mac. thx, @fangpin

[iAInNet]

I think it's a proxy problem. You can export PAC file from some proxy tools such as SwitchyOmega. Then overwrite PAC file of shadowsocks.

[vaxin]

@fangpin @SiriusHsh 是的，那个PAC文件里只写了 ||tensorflow.org 加一个 .tensorflow.org 就好了

[dgl-prc]

when i add the host to my host file, i can get response when i ping www.tensorflow.org.
However, i still fail to access the web via browser.

@SiriusHsh it works! cool

that works for me too, on my old win7 desktop, thanks!!

[w1malik]

@SiriusHsh Thanks dear same issue with me and I am also using shadowsocks on windows 10. By changing the configuration setting from PAC to Global, it solved my issue very thanks.

Thank you! I get it!
