I also have this problem on two machines. One is my real computer which has occurred only twice (once I had the internet adapter installed, which would make sense) and the other one it was random (I was playing a MMO at that point I think), both these errors happened in the same day, but at approx. 5 hours difference. The second one is a VM, this one is giving the error every time I start it or randomly during the usage. The VM is mostly used for work, so the internet is working every time I use the VM.
Also this is the lookup:
nslookup avcloud.e5.sk (Host)

The problem with VM started to appear from 04 December 2020 and it continue.
I attached iris logs (from VM) below. I couldn't reproduce this problem on the host PC, maybe as @itman said, on the host it occurred only once or twice when I was connected to the internet so they might have done maintenance.
Both Windows installations are using ESET Internet Security, version 14.0.22.0.
