If the server requires to be accessed via a tenant, you can specify it by adding the tenant details to the LRE Server field.
Example: myserver.mycompany.net/?tenant=fa128c06-5436-413d-9cfa-9f04bb738df3 or 182.138.255.1/?tenant=fa128c06-5436-413d-9cfa-9f04bb738df3 or myserver.mycompany.net:81/?tenant=fa128c06-5436-413d-9cfa-9f04bb738df3
