Hi all,

 

after a cold restart of my unraid server (safeguards off), my unraid server does not reach the DNS server anymore, resulting unraid web offline (NETWORK: getaddrinfo ENOTFOUND mothership.unraid.netCLOUD: Socket closed), Dockers cannot be checked for updates and so forth.

 

Logs are attached, but what can I do in order to restore it?

 

Best wishes

Delete/rename /boot/config/network.cfg and reboot, that will revert the LAN settings to default DHCP, see if it helps.

That did not help either

Then it suggests a network problem, try simplifying your network as much as possible, even if just for testing, connect the server directly to the router without any firewall, etc.

Did you enter the same static dns server again?

Duh, stupid me, its probably DHCP doing it. Anyway the dns server on 5.X.XXX.112 is dead

Where to add the server twice?

Try adding 1.1.1.1 or 8.8.8.8 as dns in unraids networksettings and see if that fixes it.

The Server under 5.X.XXX.112 doesnt seem to have a dns server running

In settings, I can only set up one ipv4 and ipv6 DNS server 

you have to set it to static
 

Or change the DHCP Server settings to not hand out the 5.x.xxx.112 server as dns server.

I set it to static and the DNS server is a valid server which responds if you ping it

 

"Basic" dns server run on port 53 tcp/udp. A ping works over icmp. Those are 2 different shoes.

If youre so eager to use that particular server as dns server, i would advise you to actually setup a working dns server on there

Ok, credits to you, Google DNS servers seemed to solve the problem.
