How to fix DNS for svc.cluster.local in k3s?

My k3s cluster stopped resolving DNS name for service ClusterIP. I wonder if there is a fix?

Here is an example demonstrating the problem: the actual IP for my ClusterIP service is 10.43.153.152. When I run nslookup, I get the correct name. However, when I run ping for this name, I get a different IP address which is incorrect

/srv $ nslookup 10.43.153.152
Server:         10.43.0.10
Address:        10.43.0.10:53

152.153.43.10.in-addr.arpa      name = web-ui.smart-progress-or.svc.cluster.local

/srv $ ping web-ui.smart-progress-or.svc.cluster.local
PING web-ui.smart-progress-or.svc.cluster.local (91.195.240.12): 56 data bytes
64 bytes from 91.195.240.12: seq=0 ttl=42 time=37.107 ms
^C
--- web-ui.smart-progress-or.svc.cluster.local ping statistics ---
1 packets transmitted, 1 packets received, 0% packet loss
round-trip min/avg/max = 37.107/37.107/37.107 ms
