DNS is also one of the times when you need to know a number instead of a name, for obvious reasons. Google's DNS server is easy to remember for testing purposes. It's 8.8.8.8
but it is not true. I can get to cloudflare.com in my browser.
Why does Fing say there is a problem, when there is not?

It short, your browser may be using a different DNS to your system, which is the one Fing would be testing. DNS outages can also be quite short-lived.
I am running Fing Desktop on a MacBook Pro with the latest macOS Catalina release. I had some trouble over the last few days with my Virgin Media Business Broadband, but it is now working fine.
Fing reported the DNS issue at 5:34 this morning, having decided everything was working at 4:32.
I have no DNS servers within my network and I can ping cloudflare.com successfully, as well as browse to it.
I therefore can't understand why Fing thinks it can't resolve cloudflare.com. It looks like a bug in Fing.

I also run a mainly Mac set up. The Windows PC I tend to shutdown when not in use as it's a bit more energy hungry (OK, a LOT more!), so I've not got a comparable experience with the Windows version of Fing's desktop application.
I deliberately refreshed the Fing report and cleared my DNS cache before reporting this issue. Recent refreshes have caused Fing to test ieee.com and microsoft,com. Fing cannot resolve them either, even though I can ping them successfully.
This is a bug in Fing.

Can you share the screenshot of the report? The alert refers to the DNS not responding at that point of time. If you refresh and rescan the network and still face the same issue, please let me know.

I now have a clue about what is going on. My MacBook Pro is connected to my network with an Ethernet cable, but I also have wifi enabled, because otherwise handoff to & from my iPhone and iPad do not work.
The DNS issue was reported when Fing said the machine was connected by the Ethernet connection. For some reason, it decided at 10:26, about 20 minutes ago, that the wifi connection has joined the network. My MacBook Pro is now reported as being on the wifi, and the DNS issue has gone away. Fing had been reporting that I was on the Ethernet connection for many days.
Having joined the network with wifi, my ISP is misreporterd as Hydra Communications, when it is really Virgin Media, but that might be related to me enabling NordVPN.
If I turn off wifi, I can still ping all the DNS test sites that Fing said could not be resolved.
All of these reports are after refreshing Fing, so they are not left over from previous incidents.

While I was away from my MacBook Pro, Fing reported connectivity problems at 14:18 BST, about thirty minutes ago. At 14:21, it reported that DNS resolution is not working. My network connection had switched back to the wired connection, which Fing reports as "Connected via Ethernet at 1 Gbit".
So, every time the MacBook Pro decides it is on the wired connection, it reports that DNS resolution is not working, even though it is.
Once it decides it is connected on wifi, the issue disappears.
It may well be that the wifi goes to sleep when I am away from my machine, then eventually wakes up again, once I am using it.

Is the error appearing with both Wired and Wireless connection to your MacBook? Also, Was the computer in sleep mode during that time?

I was using my machine at 16:01 when it reported I had connectivity problems on the wired connection. At 16:10, it reported that DNS resolution was not working.
It appears that this error is only reported on the wired connection, but the machine does not have to be asleep.

Can you please share the healthcheck report with me privately when connected to Wired connection?
