i have the port 80 open and forward to the ip 192.168.1.90 but i cant connect from the outside, only inside the network.
but if i connect inside the network via wifi and then disconnect wifi (still connected by 4G), i'm still able to control the duet.
i have an arduino Yun and i can control it from the outside with no problems at all!!!

best regards

i'm having the same issue here and i need to solve it too!!!

best regards

problem solved. thanks again

thanks
