Connection refused

[TomSAVU]

Hi,
Which could be the issue for which, when trying to connect to the robot on 192.168.1.10, I can't connect and the messages are
192.168.1.10 refused to connect.
ERR_CONNECTION_REFUSED

It did work before from this computer.
The robot is answering to the ping command and I can connect normally from another computer.
I tried also deactivating the antivirus, closing the wi-fi connection, rebooting the robot.
