DeviceCodeCredentialBuilder fails to acquire token with device code

まず SDK 6.39.0 で DeviceCodeCredentialBuilder のフローを再現し、6.37.0 と比較してから、IdentitySyncClient.authenticateWithDeviceCode と、スタックトレースに示されている MSAL の instance-discovery パスを調査します。SSLHandshakeException または PKIX path-building failure が発生せずにデバイスコード認証が成功すれば完了です。

Describe the bug

It fails to even launch the default browser to allow a user to login..

code :

final DeviceCodeCredential credential = new DeviceCodeCredentialBuilder() .clientId(appId) .tenantId(tenant) .challengeConsumer(challenge -> { try { //System.out.println("HSGraph Challenge URI = " + challenge.getVerificationUrl()); System.out.println(challenge.getMessage()); Desktop.getDesktop().browse(new URI(challenge.getVerificationUrl())); Toolkit.getDefaultToolkit().getSystemClipboard().setContents(new StringSelection(challenge.getUserCode()), null); }catch(IOException | URISyntaxException e) { e.printStackTrace(); } }//end of challenge lambda ) .build(); credential.authenticate(); graphClient = new GraphServiceClient(credential, appScopes);

Expected behavior

Up until last week (5/18/2025) I can launch the Default web browser and have the user login to authenticate the app using the DeviceCodeCredentialBuilder

How to reproduce

So this is the code I use to create the DeviceCodeCredentialBuilder so any call using that throws an error.

final DeviceCodeCredential credential = new DeviceCodeCredentialBuilder()
.clientId(appId)
.tenantId(tenant)
.challengeConsumer(challenge -> {
try
{
//System.out.println("HSGraph Challenge URI = " + challenge.getVerificationUrl());
System.out.println(challenge.getMessage());
Desktop.getDesktop().browse(new URI(challenge.getVerificationUrl()));
Toolkit.getDefaultToolkit().getSystemClipboard().setContents(new StringSelection(challenge.getUserCode()), null);
}catch(IOException | URISyntaxException e)
{
e.printStackTrace();
}
}//end of challenge lambda
)
.build();
credential.authenticate();
graphClient = new GraphServiceClient(credential, appScopes)

SDK Version

6.39.0

Latest version known to work for scenario above?

6.37.0

Known Workarounds

It worked on raspberry pi running Debian 12.
It was working with Firefox as the default but that stopped working. It hasn't been working Chrome or Edge.
