   An additional check is required whether the server is accessible. Currently, it just blindly tries each of the API requests:
   
   ```
   2024/02/06 09:59:30 Failed to create domain due to: Get "http://10.0.35.120:8080/client/api/?apiKey=LIN6rqXuaJwMPfGYFh13qDwYz5VNNz1J2J6qIOWcd3oLQOq0WtD4CwRundBL6rzXToa3lQOC_vKjI3nkHtiD8Q&command=createDomain&name=Domain-PIcJCkazXi&parentdomainid=7e12782c-c3fb-11ee-bcc6-1e002000040b&response=json&signature=o0uRUi7kQ4nOABlxYWO%2F8o1CtB0%3D": dial tcp 10.0.35.120:8080: connect: connection refused

   ```
   
    and even though these are failing, it reports this:
   
   ```
   time="2024-02-06T09:59:30+02:00" level=info msg="Created 1000 domains in 2.21 seconds"
   ```
   
   Note: The final table is showing the proper result:
   
   ```
