Greetings Marianne!
Everything works fine by now.
I was trying to configure robot right through the Devices-> Robots-> New Robot , and it didn’t work. Also tried with the tpconfig -new robot and it didn’t work either.
But when I tried the Configuration Wizard (Prefer to use it as a last resort because of a fair amount of loading time) the discovery had finished successfully.
My apologies for bothering,
