To allow subdomains in the development mode, you need to update the applicationhost which you can find under {solution folder}.vs\SpaApplication.MultiTenant\config\applicationhost.

<binding protocol="https" bindingInformation="*:44343:idsa.localhost" />
<binding protocol="https" bindingInformation="*:44343:contoso.localhost" />
<binding protocol="https" bindingInformation="*:44343:kiqbal.localhost" />
