I managed to sort the above warning. I then set up the port forwarding and attempted to access the webUI of the router. However, I got an empty response error.
Could this be due to the fact that there is a container set to port 80 on this device? I tried stopping the container but this didn’t solve the issue.
I have found some posts on the internet that suggest replacing localhost in the commands with 127.0.0.1 on Windows to force IPv4 mode. Please give this a try and let us know what happens.
