I am unable to access the server after a power outage. The server seems to be setting an IP address that cannot be accessed.

I have attached a screenshot here, I am baffled, i just looked up how to check network config. Any ideas on what could be the cause and if there are any commands I should run to set this back to normal?

The 169 is a DHCP address, meaning that it was unable to obtain a proper IP address from your router within the set time. When it went searching for IP.

Here's some unraid web terminal things to check and double-check...

Run these in Unraid terminal:

# Show all IPs/interfaces
ip -br addr

# Show default gateway
ip route

# Show which gateway the server would use
ip route | grep default

*Find your main NIC, usually br0, eth0, or bond0.

# Replace br0 if your interface is different
IFACE=br0

Default should be br0...

# Show IP on that interface
ip addr show "$IFACE"

# Show DHCP lease info if present
cat /var/lib/dhcpcd/*.lease 2>/dev/null
cat /etc/dhcpcd.duid 2>/dev/null

Steps to Release/reacquire DHCP:

IFACE=br0

This will set the variable for future items targeting the necessary interface. default should be br0...

# Drop current DHCP lease
dhcpcd -k "$IFACE"

# Request a fresh DHCP lease
dhcpcd "$IFACE"

Verify dhcp data received.

# Recheck IP and route
ip -br addr
ip route

Ping gateway:

GW=$(ip route | awk '/default/ {print $3; exit}')
echo "Gateway is: $GW"
ping -c 4 "$GW"

Ping the Internet IP and DNS:

ping -c 4 1.1.1.1
ping -c 4 google.com

Script One-shot full check:

IFACE=br0
echo "=== IPs ==="; ip -br addr
echo "=== Routes ==="; ip route
GW=$(ip route | awk '/default/ {print $3; exit}')
echo "=== Gateway: $GW ==="
ping -c 4 "$GW"
echo "=== Internet IP ==="
ping -c 4 1.1.1.1
echo "=== DNS ==="
ping -c 4 google.com

If DHCP renew fails, restart networking from the Unraid GUI or use:

/etc/rc.d/rc.inet1 restart

Then recheck:

ip -br addr
ip route
ping -c 4 "$(ip route | awk '/default/ {print $3; exit}')"

added cod blocks... basic linux networking commands for dhcp / IP

I have been fumbling around with your instructions not knowing exactly what I am doing but here is a screenshot

The server is not getting an IP from the DHCP server, typically your router. Post the diagnostics to see if there's something more visible.

Thats the APIPA Adress range (Automatic Private IP Adressing) - normal, if there is no DHCP-Server...

Try rebooting your DHCP server, likely your router as Jorgeb said. If that doesn't do it, reboot every network device (switch) in between DHCP and your unRAID.

Can also assign address manually in unRAID. Be sure to use a valid dns address like 208.67.222.222 or 9.9.9.9 or others.

How are you getting these screenshots if your server can't be reached on the network?

The screenshot and pictures appear to be a QEMU VM spice connection / ipmi connection...

type diagnostic and this will make and add a file onthe usb that you can post to the form for the mod JorgeB to inspect...

you typed teh comand worng its

dhcpcd

not dhcp...

You somehow managed to "correct" someone's typos with 9 of your own, 2 being in the exact commands... Maybe just don't answer.
