[6.10+] NETWORK PROBLEMS JUST UPGRADED TO 6.10.3: DESTINATION HOST UNREACHABLE

[leawhig]

Recently upgraded, but I don't know if the network is good or bad

"WAN good or bad ,LAN OK"

pinging the internet fails: Destination Host Unreachable  (first and second jpg)

 

Please help me because I can't directly generate diagnostics either (keeps stuck on this screen:third jpg)

/boot/log is still the generation of diagnostics

Delete/rename /boot/config/network.cfg so it will go back to defaults and then check if the server and get an IP address from the DHCP server.

it's not working 

Whenever I delete network.cfg and reboot, as soon as I change the IP

I'll get the above situation.

Don't change the IP, see if the server gets one from the DHCP server, if it doesn't there's a problem there, or with how the serve is connecting to it.

I am waiting for DHCP to get IP success, and then change the static IP

 

 

But after the change will not be able to get the IP, the NIC light from a bright to not light

[JorgeB]

And with DHCP it works?

Do you have more than one NIC?  Can you check that the MAC address showing for the NIC assigned to Interface eth0 actually matches the MAC address of the physical adaptor?  Under interface rules, you can choose the NIC order.

Yes , other server can get IP.

By the way , i have  Passthrough two nic

I don't know if this will have an effect?

If I'm reading this right, you have two NICs on the new server?  In that case, the likely problem is the order of the NICs is opposite to what you think.  Boot into GUI mode and swap them here:

My UNRAID has only one NIC

All other NICs are Passthrough to vm.

Is the IP attributed by the DHCP server in the same subnet? Or just use that one.

Use DHCP, no need to set Static IP, reserve IP by MAC address on the router.

[leawhig]

ohh... That solves it!

I connected the keyboard to manually reboot the machine.

There seems to be something wrong with the webUI edit
