Raspberry Pi 3 to NAS doesn't work the explorer interface

Hello,

I have istalled the OMV_3_0_79_RaspberryPi_2_3_4.9.35 on my Raspberry PI 3, and after a lot of tries I managed to get IP from the WIFI. I tried with this IP to connect on the Raspberry through Chrome, but I got back the message:

This site can’t be reached

169.254.5.87 took too long to respond.
Try:

• Checking the connection
• Checking the proxy and the firewall
• Running Windows Network Diagnostics

ERR_CONNECTION_TIMED_OUT

how I can confirm that the Raspberry has been setup correctly?
I would like to inform you that I am not familiar with linux/Raspberry etc... so all my tries has been done after a lot of reading on internet.

Can someone help me please?

Thank you in advance

First of all I would like to thank you for your answer.

I tried what you asked and below is the results.

C:\Windows\system32>ping raspberrypi ping raspberrypi.local
Ping request could not find host raspberrypi. Please check the name and try again.

Also I attached and one photo of the terminal in raspberrypi

C:\Users\Vasilis>ping 192.168.2.21

Now, sometimes under my computer/network I can see the "computer" named: RASPBERRYPI but is not accessible.

From RaspberryPI side is working the ping.

Hello,
For some reason after 1 day, during the day raspberry pi was OFF, today when I turned it ON, everything works fine.

I managed to connect through the web GUI and create share folder which now is visible from my computer.

Now, I am trying to remove(un-mount) the existing USB that I installed but is not possible. The unmount button is gray-out.

How can I unmount the USB?

Could some one help me, please?

I found it,

I had to delete the shared folder from SMB/CIFS -> shares their firstly, and then I had to delete it from shared folders tab.

Always I had the Ethernet disconnected.

Now I have another question. How can I share a folder that is already on my HDD? let's say I have already the folder named "backup" created, with files inside. How can I share this folder through Openmediavault Web GUI?

Thank you again.

Is not possible to move the older folders to the new shared folder through the Raspberry PI, correct? Have I to do it from my PC?

Thanks once again for the help.

Hello,
Finally, I managed to program the Raspberry PI to work correctly.

Thank you for the help!!
