Change network server to US_902_928 not working :(

Hello, I’m new here and i’ve been trying to install correctly and receive data on the application server for a while, and I found this error trying to debug. Can you help me?

This is my Network-server settings on chirpstack-network-server.toml, i use chirpstack-network-server-us915.toml as a reference.

`# Network-server settings.`
# Network identifier (NetID, 3 bytes) encoded as HEX (e.g. 010203)

  # LoRaWAN regional band configuration.
  # Note that you might want to consult the LoRaWAN Regional Parameters
  # specification for valid values that apply to your region.
  # See:

    # LoRaWAN network related settings.
    # Enable only a given sub-set of channels
    # Use this when ony a sub-set of the by default enabled channels are being
    # used. For example when only using the first 8 channels of the US band.
    # Note: when left blank, all channels will be enabled.
    enabled_uplink_channels=[0, 1, 2, 3, 4, 5, 6, 7]

    # Class B settings
    # Ping-slot data-rate.

    # Ping-slot frequency (Hz)
    # Set this to 0 to use the default frequency plan for the configured region
    # (which could be frequency hopping).

However, even after running:
sudo systemctl start chirpstack-network-server.service

I got this:

It looks like your database credentials (or the path) are incorrect. Is victor the user you intended to connect with from the network server?

Yes, I installed the network server and the application server on my PC, and on the gateway I installed the packet foward and gateway bridge.

I don’t know if this helps, but my packet foward came from here:

You are need to check the PostgreSQL and chirpstack-network-server.toml with database, user, password, and connection settings at the both sides.

I found my error when uninstalling and installing again, thanks for the tips guys.
