IdentityServer4 Correlation Failed Error with External Provider

问题

I am attempting to integrate Ping Federate as an external OIDC provider for my IdentityServer4 instance. When I initiate the external login flow I am getting the following error:

System.Exception: Correlation failed.

I'm kind of stumped on why FederatedSignOut is even being called. Any ideas on what I may be missing here?

Here is the AddAuthentication configuration:

services.AddOidcStateDataFormatterCache();

services.AddAuthentication()
            .AddOpenIdConnect("ping", "Ping Federate", options =>
            {
                options.SignInScheme = IdentityServerConstants.ExternalCookieAuthenticationScheme;
                options.SignOutScheme = IdentityServerConstants.SignoutScheme;

                options.Authority = "https://ping.domain.com/";
                options.ClientId = "IdentityServer4";
                options.ClientSecret = "IdentityServer4";

                options.TokenValidationParameters = new TokenValidationParameters
                {
                    NameClaimType = "name",
                    RoleClaimType = "role"
                };
            });

Add this in the configuration in startup.cs. Its an issue with going from http to https.

app.UseForwardedHeaders(new ForwardedHeadersOptions
        {
            ForwardedHeaders = ForwardedHeaders.XForwardedProto
        });
