Network Link Down

Connection failed. I have been checked routers and internet connectionnall good. Changed port from 80 to 81 and from 443 to 444 at WD my cloud mirror.It worked for an hour and same issue come back connection failed.

Thank you for any help.

Have you tried turning off and on remote access as well as a device reboot or soft reset?

I think it is better to use the Ports 80 and 443. Try it again and Try to Restart the Router and the MCM.
