New firmware 2.31.149 for Cloud EX2?

WD My Cloud App doesn’t connect with the cloud anymore ? App find the device and show correct IP adress, but then get an error after update for 2.31.149ver.


@blk Support questions probably doesn’t belong into a firmware release thread.


I have the same problem after update to 2.31.149 firmware version.
My Cloud App (windows version) does not connect anymore to the NAS from remote.
Thank you in advance
