Cannot access NAS from One User

Hello!
Yesterday, I came back to my computer, only to find I cannot access my NAS. I went on another computer in my house, attached through LAN and it worked. I also went to another user on my computer and it worked, but on my user it did not. Naturally, I tested and attempted to find why and failed. I tried doing this to my NAS (medianas1) in cmd:

Code:

ping medianas1

And this was the result:

Code:

Pinging medianas1 [192.168.2.8] with 32 bytes of data:Reply from 192.168.2.8: bytes=32 time<1ms TTL=64

    Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 0ms, Maximum = 0ms, Average = 0ms

From the Network tab of file manager, I was able to see medianas1, but when I double clicked to open it, the following message came:
"\\MEDIANAS1 is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions.
A specified logon session does not exist. It may already have been terminated."
I also did this in cmd(Public is a folder in medianas1):

Code:

net use \\medianas1\publicSystem error 1312 has occurred.


A specified logon session does not exist. It may already have been terminated.

Also during the same day, I got a new ISP and a power failure had happened the previous night (without UPS).
Thank you in advance.
