How to set DNS server?

Support Network

I added the DNS server in the System-Settings, but it doesn’t appear to propagate (I also tried setting the method to manual and automatic (only addresses)) ?

( nmcli dev list || nmcli dev show ) 2>/dev/null | grep DNS
IP4.DNS[1]:                             192.168.0.1
IP6.DNS[1]:                             2a02:8070:b590:ca00:6e63:9cff:fe4a:65f5

192.168.0.1 is the router. There is no DNS-Server setting on that router.

Problem is I cannot resolve slack.com from my Desktop or phone when connected to said router, but I can resolve it when using mobile internet, hence why I am trying to change the DNS-server.

Slack is down for today.

The DNS is from your router. You should check of you can set the upstream DNS directly in your router’s settings. This way, all your devices use it.

unfortunately, already looked for that. Will need to buy a different router

Ah sorry, I misread you post.

The above message should give hints. The NetworkManager GUI should have the option to set the DNS. Your setting is the “alternative” servers that are probably not used as the primary server.

The first answer has the instructions in the first link.

Rebooted the machine and now it has picked them up. Can connect to slack again :slight_smile:

Perfect, a restart of NetworkManager or a reconnect of your network should have sufficed but a reboot can’t hurt.
