I just recovered from weird issue. Router was unable to ping anything (by IP address) in local, or any connected network.
I catch that because I have netwatch rule that is watching our main connection and in case of failure it is switching to backup connection.
Netwatch is pinging every 30 seconds to my ISP's gateway.
I can't ping anything from tools/ping and tools/netwatch, but IPScan is running as well as traceroute. But router itself was responding to the ping requests.
My configuration is CHR on Hyper-V 2019. Version is 7.3.1, uptime 13 days.
It starts working instantly after CHR's reboot.
Do you ever face a such behavior?
