How to know Identity server is down using app.UseIdentityServerBearerTokenAuthentication( New IdentityServerBearerTokenAuthenticationOptions()

[jitender82]

We are using app.UseIdentityServerBearerTokenAuthentication( New IdentityServerBearerTokenAuthenticationOptions() With { .Authority = "https://first.com:443", .ValidationMode = ValidationMode.ValidationEndpoint, .ValidationResultCacheDuration = New TimeSpan(0, 0, 200), .EnableValidationResultCache = True, }) in our web API and on https://first.com:443 our identity server is running which validate the token. How could we know that identity server is down ?
