My Device is Offline again :(

If you have SSH enabled, you can try "apachectl restart" it should restart the web server that provides the GUI. I doubt this would work since a reboot or an OS reinstall should have worked but you may get a useful error message.

Thank you xeltros!

I got this:

root@Andrenalins_nas:~# apachectl restart
[Wed Sep 17 16:49:36 2014] [warn] Useless use of AllowOverride in line 7 of /etc /frontview/apache/READYDROP.conf.
[Wed Sep 17 16:49:36 2014] [warn] Useless use of AllowOverride in line 4 of /etc /frontview/apache/apps-https.conf.
apache2: Could not reliably determine the server's fully qualified domain name, using 192.168.1.79 for ServerName
root@Andrenalins_nas:~#

Those are harmless warnings. Is the interface working now ?

no not yet...

Do you have add ons installed ?
what df -h shows for the / (rootFS or /dev/md0 they are the same I think) ?
Did you enable iptables ? or made any config via SSH that could impact the web server or the network connectivity ?

mmhi do not know what iptables are and i did not changed anything via ssh because i am not a pro in this^^ Right after the Power blackout i got that behavior of device is offline.

i had plex installed but i did this some days ago and everything worked fine

Ok, so summary :
- Device works except the GUI
- SSH was enabled but never used (by you anyway)
- You already had the problem and support solved it
- OS reinstall or reboot do not solve the problem
- from what you've shown the / partition still has room, and the web server is running fine...
- only addon installed was plex

Did you try both http://ip and https://ip ? does https://ip/admin works ? Do you have something on screen or is it the browser default page for unavailable resource ?
Depending on that it may be the rights on the files, perhaps...

To be honest I am exhausting my options here, I'll try to find other things to test but you may want to create a case via mail and ask them to solve it AND tell you how they did it. If you ask nicely I'm sure they will tell you what was wrong and which commands they used.
Also I would backup the data while it is accessible (it should already have been done). It is possible that a factory default would solve this definitively.

thanks for your help so far i really appreciate it.

No problem, but I'm running out of potential causes.
We excluded network problems (unless you have a professional firewall somewhere) and the web server seems to be running fine.

We can check that it is listening on the network :
netstat -na |grep LISTEN |grep ':80\|:443'
and in config files :
cat /etc/apache2/ports.conf

We can also check that apache is indeed running :
ps aux |grep apache

Depending on what the browser shows it can be user rights so we can also check the rights on the files :
ls -l /frontview/dashboard
It should show something like this -rw-r--r-- 1 root root for most files, I have drwxr-xr-x 2 root root for a few other and -rw-r--r-- 1 115 guest for dictionary and favicon.

Last thing I can think of is lack of memory :
free -h
cat /proc/meminfo

Past that, I fear I have no more ideas for the moment...
