Event Protoscan Proxy Agent Cannot read from socket: Host is down root

[Jeff Miller 0]

I get tons (40+ a day) of this Event "Protoscan Proxy Agent    Cannot read from socket: Host is down root"

macOS Sierra Version 10.12.6 (16G2016)

Eset detection engine 19682

Detection engine used in last scan 19488

Why is the scan engine older?

For this issue it will be necessary to open a support ticket for your local customer care.

If the program doesn't update the engine and it stays at 19488, there should be some errors in the ESET Event log. What are they?
