Can we set a static issuer in Identity Server 4?

Question

The access token in response contains the following claims:

"alg": "RS256",
"kid": "143e829c2b57489969753ba4f8205979df0da988c640cffa5f1f4eda1b6e6aa4",
"typ": "JWT"
"nbf": 1481451903,
"exp": 1481455503,
"iss": "https://localhost:44350",
"aud": [ "https://localhost:44350/resources", "customAPI" ],
"client_id": "oauthClient",
"scope": [ "customAPI.read" ]

And here is the config to tell my application to use IdentityServer to authenticate

app.UseIdentityServerAuthentication(
    new IdentityServerAuthenticationOptions
        {
            Authority = "https://localhost:44350/",
            ApiName = "customAPI",
            ApiSecret = "secret",
            AllowedScopes = {"customAPI.full_access", "customAPI.read_only" },                
            RequireHttpsMetadata = false
        });

How do I allow the user to authenticate on different alias of the IdentityServer aside https://localhost:44350/ e.g : http://192.168.1.20:44350/?

As currently the token get from the latter domain is deemed as invalid on my client which has the Authority setting to the former domain.

You can set a static issuer name when adding IdentityServer in the ConfigureServices method. It's on the options passed into AddIdentityServer.
