We couldn't sign you in. Please try again - azure-active-directory

Question

I'm getting the error We couldn't sign you in. Please try again. when I try to login to my custom web app that uses Azure AD. The client secret expired so I figured I could just create a new one and replace it to see if that fixes it. However my current app doesn't seem to have a client secret.
I used a lot of boilerplate code to set this up originally so I don't know what's going on with this to be honest. Below is my Startup.cs file where I pull the client ID and other stuff from the web.config file. Notice a lack of client secret.
public partial class Startup
{
private static string clientId = ConfigurationManager.AppSettings["ida:ClientId"];
private static string aadInstance = EnsureTrailingSlash(ConfigurationManager.AppSettings["ida:AADInstance"]);
private static string tenantId = ConfigurationManager.AppSettings["ida:TenantId"];
private static string postLogoutRedirectUri = ConfigurationManager.AppSettings["ida:PostLogoutRedirectUri"];
private static string replyUrl = ConfigurationManager.AppSettings["ida:ReplyUrl"];
private static string authority = aadInstance + tenantId;
public void ConfigureAuth(IAppBuilder app)
{
app.SetDefaultSignInAsAuthenticationType(CookieAuthenticationDefaults.AuthenticationType);
app.UseCookieAuthentication(new CookieAuthenticationOptions());
app.UseOpenIdConnectAuthentication(
new OpenIdConnectAuthenticationOptions
{
ClientId = clientId,
Authority = authority,
PostLogoutRedirectUri = postLogoutRedirectUri,
RedirectUri = replyUrl
});
}
private static string EnsureTrailingSlash(string value)
{
if (value == null)
value = string.Empty;
if (!value.EndsWith("/", StringComparison.Ordinal))
return value + "/";
return value;
}
Can someone point me in the right direction? Or it may be something completely different. After I login it does a bunch of redirects and ends up with the error mentioned above.

Turns out I was accessing the original URL on http and not https and that was causing an issue.
