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 ?
