IdentityServer 4遇到问题

配置授权地址错误，导致出现下面问题：

 

需要检查Authority 地址是否有效

AddOpenIdConnect("oidc", options =>
{
options.Authority = "http://x.x.x.:80";
options.RequireHttpsMetadata = false;
options.ClientId = "xxxx";
options.ClientSecret = "d0296214-ff08-2987-b6ba-50bbf6838cc2";
options.ResponseType = "code";
options.Scope.Add("openid");
options.Scope.Add("email");
options.Scope.Add("profile");
options.Scope.Add("roles");
options.GetClaimsFromUserInfoEndpoint = true;
options.TokenValidationParameters.RoleClaimType = "role";
options.TokenValidationParameters.NameClaimType = "name";
options.ClaimActions.MapUniqueJsonKey("role", "role");
options.ClaimActions.MapUniqueJsonKey("nickname", "nickname");
options.SaveTokens = true;
});
