Thanks for your answer! This morning I started Maya... I was not connected to the internet and I noticed that in this situation the error does not appear... I couldn't check it better, but could it be that the error in question was caused by mIRC, which usually opens other ports and that I was using yesterday when the error message appeared in the Command Feedback line? Anyway, does this represent a problem for the functionality of Maya? Why, however, Maya should be try to listen to that port? Thanks again!
