SOAP error: failed to load external entity

[rob....@euautomation.com]

I've started getting this error over the last couple of days, but I've only just noticed today. It is not just the "CampaignService", I'm also getting it on the "AdGroupService". Here is the stack trace for the error.

SoapFault exception: [WSDL] SOAP-ERROR: Parsing WSDL: Couldn't load from 'https://adwords.google.com/api/adwords/cm/v201702/CampaignService?wsdl' : failed to load external entity "https://adwords.google.com/api/adwords/cm/v201609/CampaignService?wsdl"

 in /var/www/html/vendor/googleads/googleads-php-lib/src/Google/AdsApi/Common/AdsSoapClient.php:65

I've tried loading the file over curl from the same server and it works perfectly.

Hi Rob,

Could you try and see if the instructions mentioned here resolves your issue? If it doesn't, please create a new issue on the PHP client library and share your error logs there. The PHP library owners are better equipped to assist you. 

Best regards,

Hi Peter,

Thanks for getting back to me. I had a go at instructions and they didn't help, but I've manage to fix it now. Adding this line of code managed to fix it.

libxml_disable_entity_loader(false);

I future I shall go there first. :)

Kind Regards,

Rob
