cURL error 56: Proxy CONNECT aborted

[TriNguyen1992]

Hi,
I've been working with Google AdWords Api for a few days recently, and I got this error from running getCampaigns.php via command line but I haven't figured it out yet even I tried a lot. Please help me out. Anyway, I use XAMPP on Window10
many thanks,

Hello,

It looks like you have a problem with your proxy settings.
Do you use a proxy to send requests to AdWords API?
Could you please check that the proxy allows such communication?

Best,
Knack

Hi @fiboknacky , thanks so much for your quick reply.
I'll check and get back to you ASAP ^

[TriNguyen1992]

I did the settings: I turn Use setup script on, in adsapi_php.ini I configed proxy = "http://localhost:443" as I work localhost on window10 but it still didn't work for me, I just wonder what was I missing?

[fiboknacky]

So your proxy is installed in localhost?
Can you use your proxy to send requests to other services / APIs?

So your proxy is installed in localhost?
-> I just followed exactly what's in the Adwords Api Doc says, and when I execute GetCampaigns.php (On browser or in Command Line), I got the error above, or if I tried to config proxy = "http://127.0.0.1:80" I'd get the error: cURL error 56: Received HTTP code 405 from proxy after CONNECT . Do I have other choice instead of using proxy?
I've been stucking with this problem for a few days. thanks bro ^,

What doc are you talking about? Could you point me to that doc please?

In general, you have to figure out first how your proxy is configured.
I can't help on that part as I'm not able to see how your computing environment is set up.
I may help if you can try on other computers too, to see if the problem still exists.

Hi @fiboknacky , thank you so much for your patience in this case to help me bro.
Actually, at the beginning the proxy config (in adsapi_php.ini) was commented and the original error was:
_Fatal error: Uncaught SoapFault exception: [HTTP] Could not connect to host in C:\xampp\htdocs\GoogleAdwords\googleads-php-lib\src\Google\AdsApi\Common\AdsSoapClient.php:98

then I turned the proxy config on (as I read some solutions from internet) and got the error that we were talking about so far.
As the original error in this comment, do you have any idea how to fix it?

Hello,

First, if you don't have a proxy that you can use, you shouldn't turn it on.

For your problem, there are many factors that can lead to that error, such as your XAMPP isn't configured properly so you can't connect to the AdWords API servers or your SSL CA isn't installed properly.
Could you try troubleshooting using this wiki?

BTW, what version of the client library are you using?

Best,
Knack

Hi @fiboknacky , thanks bro. seems we are getting close to it.
I did as the wiki you mentioned above [put the curl-ca-bundle.crt file as in C:\Windows\System32\curl-ca-bundle.crt as well as config in php.ini file: openssl.cafile="C:\Windows\System32\curl-ca-bundle.crt" ] but then I got this error:
PHP Fatal error: Uncaught exception 'GuzzleHttp\Exception\RequestException' with message 'cURL error 77: error setting certificate verify locations:
CAfile: C:\Windows\System32\curl-ca-bundle.crt
CApath: none (see http://curl.haxx.se/libcurl/c/libcurl-errors.html)' in C:\xampp\htdocs\GoogleAdwords\googleads-php-lib\vendor\guzzlehttp\guzzle\src\Handler\CurlFactory.php:186

Do you have any idea? I'm using v201802

[fiboknacky]

Do you have any idea? I'm using v201802

No, I meant the client library version (e.g., 33.1.0), not the API.

Can you elaborate what step you tried to face with that error?
As the error message stated, you specify invalid locations for the certificate.
You have to double check if there is a certificate in that path indeed. (It seems not)
