Credential could not be refreshed, java client library version v201708

[hari krishna]

Hi,

 We are getting Credential could not be refreshed error  occasionally. We are using java client library version  v201708.

I generated new refreshToken also but that did not work to solve the issue permanently. 

Can you please help us to resolve this issue permanently. 

Below is the stack trace.

Hello Hari,

Could you try and regenerate the refresh token again by following this guide? You can refer to the example from the Java client library for generating the credentials. Additionally, could you confirm if you're generating the refresh token in every API call? If so, please note that there is a limit of 50 refresh tokens per user per account. If you're trying to generate a refresh token above the specified limit, they will be invalidated. Let me know if that works for you.

Thanks,

Bharani, AdWords API Team

Hi Bharani, 

If I generate new refresh token it will work fine. But after couple of days it is not working and i need to generate  new refresh token to make it work. 

I am following below link to generate refresh token. 

https://github.com/googleads/googleads-java-lib/wiki/API-access-using-own-credentials-(installed-application-flow)#step-2---setting-up-the-client-library

below is the code I am using. I am not generating refresh token every time. Once refresh token generated I will keep that in ads.properties( api.adwords.refreshToken=XXXXXXXXXXXXXXXXXXXXXX )

When I start my standalone java application i will call  below method only once. Please let me know is there any thing problem in this. 

 

@Override

public AdWordsSession generateAdwordsSession() {

// Generate a refreshable OAuth2 credential.

Credential oAuth2Credential;

try {

oAuth2Credential = new OfflineCredentials.Builder().forApi(Api.ADWORDS).fromFile().build()

.generateCredential();

// Construct an AdWordsSession.

return new AdWordsSession.Builder().fromFile().withOAuth2Credential(oAuth2Credential).build();

} catch (OAuthException | ValidationException | ConfigurationLoadException e) {

LOGGER.error("Error in getting AdwordsSession with given credentials", e);

return null;

}

}

Thanks!

Hello Hari, 

Your code snippet looks good. To investigate the issue further, could you provide us the logs with complete error message you received with the new refresh token? 

Thanks,

Hi Bharani, 

I have given error message above. Same Error message I am getting.It is not giving any SAOP logs for this call. I only have java error log which i have given below.  Please let me know if you need any other information. Can you please check why Refreshtoken got expired. This refresh token generated few days back and now it is throwing below error (I am using test account.)

Below property commented out in ads.properties file. Can you Please check is there anything to do with this. 

# Enable/disable automatic OAuth2 token refreshing. Default is enabled.

#api.adwords.refreshOAuth2Token=false 

Thanks!

Hari.

Hello Hari, 

To rule out issues with the client library or your ads.properties file, could you issue the access token request via curl as follows?

curl --data "grant_type=refresh_token" \

     --data "refresh_token=YOUR_REFRESH_TOKEN" \

     --data "client_id=YOUR_CLIENT_ID" \

     --data "client_secret=YOUR_CLIENT_SECRET" \

     https://www.googleapis.com/oauth2/v4/token

You won't be using curl to get access tokens from your app, but this will tell us if the refresh token, client ID, and client secret you're using are valid.

Seems this is issue with our proxy server, our proxy server changing the url and that causes this refresh token expire issue. We fixed it in our side. 

Thanks!

Hi! I am having similar issue in my server! It works fine in my local machine! Can you please elaborate how you solved?

Hi Koshish, 

Thank you for reaching out to support. Can you make sure that you're using the same set of credentials on both the machines (local and server)? If you could compare the settings used for your local machine with the server settings, it might help you pinpoint the issue. Could you also try the steps followed by Hari on this thread? If you're having an issue, please share the error logs to check this further.
