Hello together. At first sorry for my bad english.
At yesterday i had a little problem with my WDMCMG2.
Before 2 Days i flashed DSM from http://fox-exe.ru/WDMyCloud/WDMyCloud-Mirror-Gen2/DSM/
I enabled ssh at first in the DSM Settings because its importend
The Installation-Process and Setup was problemless and my WD is working fine.
I dont plugged out or shutdown over night
Next day i went again to the WebGUI but nothing happens anymore, only a blank Site.
Then I have tested some things:
Cold Restart (plug out Power)
Remove Disks and Re-insert and Restart
Pressing the Reset Button a few Times
tryed to connect via https on port 5001 is the same like http on port 5000 or 80 - only a blank Site (used Firefox and Chrome)
If I test to connect via ssh and telnet - no way because the Ports are closed
the output of nmap says
PORT STATE SERVICE
80/tcp open http
139/tcp open netbios-ssn
161/tcp open snmp
443/tcp open https
445/tcp open microsoft-ds
5000/tcp open upnp
5001/tcp open commplex-link
no ssh or telnet support 
I hope somebody has any solution for this (little) Problem
Oh and i'm using Linux/Xubuntu if its importend to find the Problem
Many thanks in advance for your help
