Thanks for reaching out.
The error you attached has showed connection timed out while calling authorize endpoint https://login.microsoftonline.com/<tenantID>/oauth2/v2.0/authorize
Did you configure the redirect URL correctly to get the authorize code?
Did you tried Microsoft Graph Client to get the access token instead of HttpClient.Reference to call MS Graph Client:
To install Nuget Package https://learn.microsoft.com/en-us/graph/sdks/sdk-installation#install-the-microsoft-graph-java-sdk
Configure graph Client : https://learn.microsoft.com/en-us/graph/sdks/create-client?tabs=JavaIf that will not help, could you please share the code snippet where you are trying to acquire the token.
Thanks

2022-07-27T05:32:18.953+00:00 Hi @Capil Verma ,
Did you try to request the token using postman with above parameters?
It seems the parameter names auth_code ,appIdUri and response_type is not valid while requesting the token with authorization grant flow.
As mentioned, here, you need to pass required parameters in http request to get the token.Thanks,

SUFYAN AHMED 0 Reputation points2023-07-24T21:43:03.3533333+00:00 we are getting intermitten issue with message -- the internet connection has timed out at microsoft.identity.client.platforms.features.winforms legacy webUI. <acquireauthorizationAsync>d_20.Movenext. it happened during the authentication. i have tried to allow everything for port 80/443 on our firewall but issue occurs sometime.
the flow starts through remote desktop app from where we get into portal and then we click the application, which pops out the login page and during that process or before we get this message frequently
