Network Link Down Alerts

I have a My Cloud EX2 Ultra 12Tb unit. Recently I am seeing random alerts for Network Link Down. The event type is 1002 and the message reads “The network link is down or has become intermittent. Check your network connection”. I have the EX2 plugged directly into a 1Gb port of my ASUS RT-AC88U router. Have moved the network cable (and changed it out) to another port. The ASUS router’s logs don’t show any corresponding network events for the time and date in question on the My Cloud.

I had opened a ticket with WD and the technician did not believe it is anything to be concerned. He said it could be related to power fluctuations. I have my router and My Cloud connected to a Cyberpower battery backup system so I don’t believe the power fluctuations is valid.

Is anyone having similar issues. Thanks

Hi,

Please refer to the given below KBA link:

Thank you for the follow up. I have performed all the recommended technical steps. Checked Ethernet cable, swapped it out, and moved the connection
to another port on my router. One suggestion I don’t fully understand is “The Port on the router is detected”. Not sure what that means or how to resolve this
issue.

Thanks

I think it means “defective” but who know with all the Chinglish in these instructions!

I don’t have the Ultra, but my EX2 has become unreliable also.

win10 logs had this error:
The certificate received from the remote server does not contain the expected name. It is therefore not possible to determine whether we are connecting to the correct server. The server name we were expecting is 192.168.0.19. The TLS connection request has failed. The attached data contains the server certificate.

Is there some sort of cert on the WD’s that needs to be kept updated in step with all the security https and TLS updates being implemented in browsers?

thanks,

I have performed all the recommended technical steps. Checked Ethernet cable, swapped it out, and moved the connection to another port on my router.

I’m having the same problems.
While troubleshooting, noticed even with Public not avail over network, WD was still pingable.

Stumbled across this article: https://support-en.wd.com/app/answers/detail/a_id/25436/related/1

  • Created non-admin account on WD (seems to have created private share at the same time)
  • Mount that dir in win10
  • It’s been 1.5 days and (fingers crossed), WD hasn’t had network interface problem (yet).
