Google ADs API "failed to connect to all addresses"

[Lee Franke]

I just need to know what domains/ports to request to open for our VPN.

If I have the VPN off, everything works as expected.

Once I turn the VPN on, I get the aforementioned error message,

Thanks!

Hi,

 

Thank you for reaching out to the Google Ads API support team.

 

By reviewing your query, I understand that you are getting a "failed to connect to all addresses" error. I would like to inform you that the error message “failed to connect to all addresses” indicates that the Google Ads API is experiencing a temporary outage. This can happen for a variety of reasons, such as high traffic volumes, software updates, or hardware failures.

Here are a few steps you can take to troubleshoot the issue:

 

• Retry the request: Sometimes, the outage is resolved quickly and retrying the request will be successful.
• Please note that the Google Ads status dashboard currently shows no reported issues regarding API requests. Check the Google Ads status page that provides information about known outages and service disruptions. You can check the status page to see if there are any current outages that may be affecting your requests.

If the issue still persists, kindly provide us with the complete API logs (request and response with request-id and request header) generated at your end.

 

If you are using a client library and haven't enabled logging yet, I would request that you enable logging for the specific client library that you are using. You can refer to the guides in Java, .Net, PHP, Python, Ruby or Perl to enable logging at your end. For REST interface requests, you can enable logging via the curl command by using the -i flag.

 

You can send the details via the Reply privately to the author option or direct private reply to this email.

 

 

Thanks,
 

Google Ads API Team

The Code is is .Net.

Like I stated in the original comment: It runs fine without VPN. Once I turn on our VPN it no longer connects. I just need to endpoints and and ports that it is using so I can put in a change request to open the VPN.

Thanks,
