Do I need to change my PI settings or router settings?

    So I have a QNAP NAS, and for some reason I have noticed recently that on occasion my Pi keep changing IP addresses. And when it does, I have to take that new IP address and add it into my NAS settings for it to see the multimedia. Is there something I should be changing on the PI to prevent this from happening, or is this something I need to fix in my EERO router? Granted I haven't changed any router or PI settings, but it appears to happen more frequently than before.

    If you are granting access to NAS shares only to specific IP's and the RPi moves around the DHCP scope, you could:

    • Configure a static address in the RPi and then allow that address on the NAS
    • Create a DHCP reservation in the router for the RPi so it is always dynamically assigned the same address
    • Create credentials to access the shares and avoid the need for IP blocking

    IMHO using a DHCP reservation (makes SSH access to the RPi consistent) and also using credentials and basic access controls to manage access to shares is the winning combination. From a security perspective IP blocking is a fairly blunt instrument.

    I tried the 3rd option which took in router settings, but still no luck. I then decide to go back to regular default settings and no luck there either. The IP address in the Pi is the same I added to the shared folder in the NAS. Usually as soon as I add the IP address the movies start working again.

    However I am getting the picture attached. Rebooted the PI, then the NAS as well, double checked I applied the settings when I added the IP address to the shared folder. Only other change is the nightlies. I wouldn't think that would be an issue, but I can try and downgrade to a previous version to see.

    I also know the files are still available because I checked the multimedia folder in the NAS and everything is still there. So I have no idea why the PI is suddenly not seeing the folder. Especially since I added the IP address to the shared folder.
