192.168.0.41 was the IP in tab "Network" (I was seeing TCP/IP Error message at startup)
Local IP's was 169.254.226.99,
I changed the IP by the local IP's (169.254.226.99) and the software worked good.
I test now the IP "127.0.0.1" and the software works good too (I didn't have this information).
Thanks for this feedback and I advise you to add this default IP information in the topic
