Question

Khoa Phan 1

Dear,

My application used Microsoft Graph for Authentication. The workflow here.

(1)Access to application -> (2)Redirect to Microsoft Login -> [Login success] -> (2)Redirect to my application with code parameter.

Step (1) and (2) It's working when my IT add 3 URLs to whitelist for Azure Server:

But in step (3), I cannot received parameter from https://login.microsoftonline.com/ , It's appear "Connection refused for URI https://login.microsoftonline.com/telnatid//oauth2/v2.0/token"

Could you please advise me for any configuration in Azure?

Thanks,

Khoa Phan

Hi @Khoa Phan This is the authorization code, next you need to redeem it for an access token. https://learn.microsoft.com/en-us/azure/active-directory/develop/v2-oauth2-auth-code-flow#redeem-a-code-for-an-access-token

Dear @CarlZhao-MSFT ,

Application is working ok, when I add proxy for request and respond https://login.microsoftonline.com/. But my IT not recommend use proxy server because this server migrated in Azure server, will open anything I want. But, nobody find root cause why Connection refused for URI.

Thanks CarlZhao
