So I have done the Onprem CRM automation using Selenium C#. 

While login in CRM Onprem on any browser, it shows the authentication popup for entering Username and Password while running the automation script.

I have written the code where the URL automatically takes username and password in encoded format, it was working fine earlier. Since few days, I am facing the issue where it is not passing the creds in Crm url, and it shows the authentication popup

Can you please suggest what should I do to run?

I am using - C# selenium

Onprem CRM Dynamic 365

The code I have used - "https://" + HttpUtility.UrlEncode(id) + ":" + HttpUtility.UrlEncode(password) + "@" + url;
