Swashbuckle.AspNetCore. IdentityServer cookie under identity server host - identityserver4

Question

I can`t login to my API via Swagger UI. I using Swashbuckle.AspNetCore 5.2.1.
For some reason identity server cookie stores cookie in API host under identity server host (not API host). Please advice:
This is Client configuration in IdentityServer:
new Client
{
ClientId = Applications.Swagger.ToString(),
ClientName = "Swagger",
AllowedGrantTypes = GrantTypes.Code,
RedirectUris = { urlsSettings.Api + "/swagger/oauth2-redirect.html" },
PostLogoutRedirectUris = { urlsSettings.Api + "/swagger" },
AllowedCorsOrigins = { urlsSettings.Api },
AllowedScopes = new List<string>
{
IdentityServerConstants.StandardScopes.OpenId,
IdentityServerConstants.StandardScopes.Profile,
Applications.API.ToString()
},
ClientSecrets = { new Secret("test-secret".Sha256()) },
AllowAccessTokensViaBrowser = true,
RequireConsent = false
}
This is Startup in API service:
services.AddAuthentication(IdentityServerAuthenticationDefaults.AuthenticationScheme)
.AddCookie()
.AddIdentityServerAuthentication(options =>
{
options.Authority = UrlsSettings.Identity;
options.RequireHttpsMetadata = true;
options.ApiName = Application.ToString();
options.ApiSecret = "test-secret";
options.SaveToken = true;
})
.AddSwaggerGen(options =>
{
options.SwaggerDoc("v1", new OpenApiInfo
{
Title = "Merchant API",
Version = "v1",
Description = "eSales Platform API"
});
options.AddSecurityDefinition("oauth2", new OpenApiSecurityScheme
{
Type = SecuritySchemeType.OAuth2,
Flows = new OpenApiOAuthFlows()
{
AuthorizationCode = new OpenApiOAuthFlow
{
AuthorizationUrl = new Uri(UrlsSettings.Identity + "/connect/authorize"),
TokenUrl = new Uri(UrlsSettings.Identity + "/connect/token"),
Scopes = new Dictionary<string, string>
{
{ Applications.API.ToString(), "eSalesPlatform API - full access" }
}
}
}
});
options.AddSecurityRequirement(new OpenApiSecurityRequirement
{
{
new OpenApiSecurityScheme
{
Reference = new OpenApiReference { Type = ReferenceType.SecurityScheme, Id = "oauth2" }
},
new[] { Applications.API.ToString() }
}
});
options.OperationFilter<AuthorizeCheckOperationFilter>();
});
