DNS troubles in Mikrotik

RouterOS General
1

Hi Guys.
I have a Mikrotik Hex - which I’m using at a little shop.
Unfortunably there’s a error somewhere I cannot find where it is.
When trying to ping directly for Mikrotik Winbox Terminal - I’m getting this:

 > ping google.com
invalid value for argument address:
    invalid value of mac-address, mac address required
    invalid value for argument ipv6-address
    while resolving ip-address: could not get answer from dns server

But when looking in dns settings - it’ll look fine.
Although I’ve have a reserved Dynamic IP from the ISP

 /ip dns> print
                servers: 8.8.8.8
        	dynamic-servers: 193.162.153.164,194.239.134.83
  		allow-remote-requests: yes
    		max-udp-packet-size: 4096
   		query-server-timeout: 0ms
    		query-total-timeout: 0ms
             	cache-size: 2048KiB
          	cache-max-ttl: 0s
             	cache-used: 19Ki

What could be the problem here.
the IPv6 Package is disabled - But each time I’m trying anything the network is slow as a 56k Modem - so how can I make this work again

Thanks in advance

Maybe connection is too slow to reach DNS server or timing out…
What is the latency to the DNS servers?

Hi,
to reach DNS server, your Routerboard needs to have a default route installed.

You can check it by:

/ip route print

and check if you have a route with dst-address=0.0.0.0/0 and gateway your Internet Router.

Hi Guys.
Thanks for a quick Reply
In my routes I have these:

 #      DST-ADDRESS        PREF-SRC        GATEWAY            DISTANCE
 0 ADS  0.0.0.0/0                          188.178.222.21            0
 1 ADC  188.178.222.20/30  188.178.222.22  WAN                       0
 2 A S  192.168.201.0/24   192.168.202.1   WAN                       1
 3 ADC  192.168.202.0/24   192.168.202.1   LAN-bridge                0

Which Should be the right setup!
When opening a terminal in Winbox - and trying to ping google.com - it’ll give the earlier described error - But when using the tool/ping windows - No problem

Try traceroute to see where the timeout comes into play

Welll - using traceroute from tool gives a empty answer -
,But am online on the router from outsite - the only thing is the network is really slow on this line.
And my guess is regarding this DNS problem.

But haven’t seen that message before regarding this issue:

 > ping google.com
invalid value for argument address:
    invalid value of mac-address, mac address required
    invalid value for argument ipv6-address
    while resolving ip-address: could not get answer from dns server

As I asked earlier, what is the latency to the DNS servers?

do you have a private IP assigned to your WAN?
Maybe start with a default config.

also, try

/ping interface=WAN src-address=188.178.222.22 address=8.8.8.8
