I know there are several threads on the same but none of the solution works for me, is there any solution. The strange thing is when I run the application in IE it works where as in Edge I got into this issue

IDX21323: RequireNonce is '[PII is hidden]'. OpenIdConnectProtocolValidationContext.Nonce was null, OpenIdConnectProtocol.ValidatedIdToken.Payload.Nonce was not null. The nonce cannot be validated. If you don't need to check the nonce, set OpenIdConnectProtocolValidator.RequireNonce to 'false'. Note if a 'nonce' is found it will be evaluated.

Here is the code

public class Startup
{
    // The Client ID is used by the application to uniquely identify itself to Azure AD.
    string clientId = System.Configuration.ConfigurationManager.AppSettings["ClientId"];

    // RedirectUri is the URL where the user will be redirected to after they sign in.
    string redirectUri = System.Configuration.ConfigurationManager.AppSettings["RedirectUri"];

    // Tenant is the tenant ID (e.g. contoso.onmicrosoft.com, or 'common' for multi-tenant)
    static string tenant = System.Configuration.ConfigurationManager.AppSettings["Tenant"];

    // Authority is the URL for authority, composed by Microsoft identity platform endpoint and the tenant name (e.g. https://login.microsoftonline.com/contoso.onmicrosoft.com/v2.0)
    string authority = String.Format(System.Globalization.CultureInfo.InvariantCulture, System.Configuration.ConfigurationManager.AppSettings["Authority"], tenant);

    /// <summary>
    /// Configure OWIN to use OpenIdConnect 
    /// </summary>
    /// <param name="app"></param>
    public void Configuration(IAppBuilder app)
    {
        app.SetDefaultSignInAsAuthenticationType(CookieAuthenticationDefaults.AuthenticationType);

        app.UseCookieAuthentication(new CookieAuthenticationOptions());
        app.UseOpenIdConnectAuthentication(
        new OpenIdConnectAuthenticationOptions
        {
            // Sets the ClientId, authority, RedirectUri as obtained from web.config
            ClientId = clientId,
            Authority = authority,
            RedirectUri = redirectUri,
            // PostLogoutRedirectUri is the page that users will be redirected to after sign-out. In this case, it is using the home page
            PostLogoutRedirectUri = redirectUri,
            Scope = OpenIdConnectScope.OpenIdProfile,
            // ResponseType is set to request the code id_token - which contains basic information about the signed-in user
            ResponseType = OpenIdConnectResponseType.CodeIdToken,
            // OpenIdConnectAuthenticationNotifications configures OWIN to send notification of failed authentications to OnAuthenticationFailed method
            Notifications = new OpenIdConnectAuthenticationNotifications
            {
                AuthenticationFailed = OnAuthenticationFailed
            }
        }
    );
    }

    /// <summary>
    /// Handle failed authentication requests by redirecting the user to the home page with an error in the query string
    /// </summary>
    /// <param name="context"></param>
    /// <returns></returns>
    private Task OnAuthenticationFailed(AuthenticationFailedNotification<OpenIdConnectMessage, OpenIdConnectAuthenticationOptions> context)
    {
        context.HandleResponse();
        context.Response.Redirect("/?errormessage=" + context.Exception.Message);
        return Task.FromResult(0);
    }
}

I tired the options available but nothing works, is there any possible solution for this

Referred to this OpenIdConnectProtocolValidationContext.Nonce was null

Please try updating your Microsoft.Owin.Security.OpenIdConnect package to match the version numbers on your other Owin packages, as discussed in this related thread.

Microsoft.Owin [4.1.1]
Microsoft.Owin.Security [4.1.1]
Microsoft.Owin.Security.Cookies [4.1.1]

Make sure you have also updated to the latest version of Chrome if you are using Google Chrome, or test in other browsers. (This guide discusses an issue with Chrome that was causing this error.)
