Hi,

This looks like a network issue at your end, you might want to investigate if your internet connection is flaky, most likely at your network or ISP level.

Cheers,

I have been getting this message also. For several months. I assume something changed with my ISP. I have to reload the page several times & then it executes.

In case it helps my PHP version details are:

I am also having this same issue.  I'm running the API on a share webhost.  I had originally thought it was an IPv6 issue with cURL.  At a loss.  I am thinking I am going to have to move this script to another host. 

[Blode Wong]

thanks for your reply.

I was testing in several network environment, but this problem is all the same.

[Blode Wong]

Hello, Lucas Schltze.

Thanks for your reply first.

I am running this script ina share web hosting too.  so i was testing in serveral environment just like bluehost, justhost, godaddy etc. but the results is the same!

BTW: The script is running fine about 2 months ago.

[Blode Wong]

important informations:

when i move this script to a new network environment, it's running fine at the first time.

Is it need cache the authToken?

[Danial Klimkin]

Hello Blode,

Please make sure your firewall allows outbound connections to google.com on HTTPS port (443). For example, try opening this link with curl / wget / lynx from server console:

  https://google.com

[Peter Crowley]

Hi  Daniel,

    I put this Curl code in after the 'require_once' but before the 'new AdWordsUser'

$curl = curl_init();

$file = fopen($localfile, 'w');

curl_setopt($curl, CURLOPT_URL, "https://google.com"); #input

curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);

curl_setopt($curl, CURLOPT_FILE, $file); #output

if (curl_exec($curl) === false)

{

echo 'Curl error: ' . curl_error($ch);

}

else

{

echo 'HTTPs test worked',$newline;

}

It did not help, I got this output on first run, then it worked when I reloaded(F5'd) the page.

/home1/mysite/public_html/ads/googlehomepage.html
HTTPs test worked
Exception: Failed to get authToken. Reason: Failed to connect to 2607:f8b0:400e:c01::54: Network is unreachable in line 84 file /home1/mysite/public_html/libraries/aw_api_php/src/Google/Api/Ads/Common/Util/AuthToken.php

Hello Peter,

Is your php compiled with the ssl support enabled? This can be controlled differently for different OS distributions. It could be checked with:

$ php -i | grep -i ssl

-Danial, AdWords API Team.

[Peter Crowley]

Yes, it looks like SSL is enabled...output from ' php -i | grep -i ssl':

openssl

OpenSSL support enabled OpenSSL Version OpenSSL 1.0.0-fips 29 Mar 2010 SSL support enabled 

[Eric Koleda]

Hi All,

I believe Lucas is correct, that this issue is related to IPv6.  This article provides some details:

http://codecorner.galanter.net/2011/06/03/solution-for-wordpress-curl-ipv6-error-network-is-unreachable/

As the author listed, if you are using PHP 5.3 then there is a cURL option you can use to force IPv4:

curl_setopt( $handle, CURLOPT_IPRESOLVE, CURL_IPRESOLVE_V4);

If not then you'll need to work with your hosting provider / ISP to properly configure your server/network to either support IPv6 or disable it. Please note this is not a problem specific to the AdWords API, and can be seen with other APIs as well:

http://stackoverflow.com/questions/11004624/failed-to-connect-to-2a032880101f03faceb00c026-network-is-unreachable-fr

The timing of this issue (about 2 months ago) corresponds with the IPv6 Launch Day on June 6th:

Best,

- Eric

[Peter Crowley]

Hi Eric,

   Thanks for all the details.

   My PHP version is 5.2.17 so the cURL option will not work. 

I will send an update explaining which path I took when I get there.

[Evgeniy Bogdanov]

Hi Peter.

If you still have this problem,buzz me tomorrow (28th August) in Skype between 14.00 and 17.00 MSK. I'll try to save your time and nerves and help to solve this strange problem.

Regards,
Evgeniy.

[Blode Wong]

Hi, Thanks to all.

 

I have solved this problem. It is caused by IPV6.

 

now , i have moved my script to another web hosting in China,  then it's running fine.

 

thanks to all again!

If you meet with this such problem the best way is to upgrade PHP and libcurl to latest versions. If you can't do this, you can apply next fix:
file: src/Google/Api/Ads/Common/Util/AuthToken,php,
function Login()

add below:
curl_setopt($ch, CURLOPT_POSTFIELDS, $postVars);

next strings:
if (defined('CURLOPT_IPRESOLVE') && defined('CURL_IPRESOLVE_V4')) {
    curl_setopt($ch, CURLOPT_IPRESOLVE, CURL_IPRESOLVE_V4);
} else {
    curl_setopt($ch, CURLOPT_URL, str_replace('accounts.google.com', '74.125.127.84', $postUrl));
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Host: accounts.google.com'));
}

Some explanation how it works: we're change hostname to IP address in URI to prevent cURL perform DNS lookup.
But we need somehow to specify which host we're requesting for, so we're adding manually our end Host in HTTP Header.

This is not best practice, but gives you time to keep your scripts working till you didn't find way to upgrade PHP or move to other server.

Evgeniy.

[Lucas Schultze]

Depends on your webhost.  I use hostmonster and their support gave me that answer that they currently don't support IPV6 connections to external 3rd parties.  

 The 'CURL_IPRESOLVE_V4' was throwing errors when I tried to use it.  Seems like it was added to one of the most recent versions of PHP.  

My solution has also been to move my adwords API script to new host.  

[RPC]

We're getting this error with Bluehost.

Are there any new fixes and if not can anyone recommend hosts that work without any of these issues?

Thanks - R.

[Evgeniy Bogdanov]

Hi R.

My previous fix in this thread do not works for you?

Can you create test account for me on your current host? I'll try to improve it.

Unfortunately Bluehost doesn't let you create extra login accounts. I spoke to their tech support last week and they said "that's a good idea, I'll suggest it". Duh.

Best option is FTP access. Not sure is that is enough?

Anyhow I've asked the developer whether he has in fact tried all of your solutions and I expect an answer soon

I still think the best option is to move host - who do you use?

R.

[Evgeniy Bogdanov]

I can use FTp, if you agree. I'm interested to improve my solution to support most of PHP configuration. But unfortunately I can't re-implement them on my hosts.

I'm prefer to not use hosting, I like virtual servers for their flexibility in setup. For example http://www.rackspace.com/

If you will move to other host, can you not terminate current subscription and give me access for it?

Regards,

Evgeniy.

OK. Thanks RPC for giving me access for his host.

I've improved my previous solution:

Library version: 3.2.2

File: src/Google/Api/Ads/Common/Util/AuthToken.php,
Function: private function Login()

Add after:

$this->curlUtils->SetOpt($ch, CURLOPT_POSTFIELDS, $postVars);

Next strings:

if (defined('CURLOPT_IPRESOLVE') && defined('CURL_IPRESOLVE_V4')) {

    $this->curlUtils->SetOpt($ch, CURLOPT_IPRESOLVE, CURL_IPRESOLVE_V4);

} else {
    $hostInfo = parse_url($this->server);
    if (!empty($hostInfo['host'])) {

    $this->curlUtils->SetOpt($ch, CURLOPT_URL, str_replace($hostInfo['host'], '74.125.143.84', $postUrl));

    $this->curlUtils->SetOpt($ch, CURLOPT_HTTPHEADER, array('Host: ' . $hostInfo['host']));

    }
}

I think that usage of this fix is not good for production servers.

Main problem here that we're using direct IP-address, not DNS-name, this can cause unexpected & not predictable problems in future.

If someone will get error like: unable to connect to host using this fix, you need to change 74.125.143.84 to new IP-address.

You can do it via operating system nslookup command. 

Type nslookup accounts.google.com, you'll get address which should be used.

Evgeniy.
