Connecting via SOCKS proxy

[Krishna Priawan]

Hi team,

I wasn't able to connect to Ads API while executing ListAccessibleCustomersResponse accessibleCustomers = customerServiceClient.listAccessibleCustomers(ListAccessibleCustomersRequest.newBuilder().build()); via SOCKS proxy (request hangs for about 1 hour) and got following exception from logs:

When I disable sock proxy configuration, the connection was established successfully and able to retrieve the results.

Here's the snippet code that setup the SOCKS proxy protocol:

System.setProperty("socksNonProxyHosts", socksNonProxyHost);

URI proxyUri = new URI(socksProxy);

String proxyHost = proxyUri.getHost();

System.setProperty("socksProxyHost", proxyHost);

if (proxyUri.getPort() > 0) {

String proxyPort = "" + proxyUri.getPort();

System.setProperty("socksProxyPort", proxyPort);

}

if (proxyUri.getUserInfo() != null) {

String username = proxyUri.getUserInfo().split(":")[0];

String password = proxyUri.getUserInfo().split(":")[1];

Authenticator.setDefault(new ProxyAuth(username, password))

}

Does the library suppose to be working using Socks proxy? If yes, is there any workaround that I can implement on my end to resolve the issue? Thank you

Hi Krishna,

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

To investigate the issue further, could you please provide the complete request and response logs, with the request-id?

If you haven't yet, logging can be enabled by navigating to the Client libraries > Your client library (ex. Java) > Logging documentation, which you can access from this link. You can provide it via Reply privately to author option. If this option is not available, then send it instead on this email address googleadsa...@google.com.


Thanks,
