Keine Verbindung zur Spamschutz-Cloud

[EURO-LOG 3]

Recently we replaced our installation of ESET Mail Security for Exchange v4 with the current version 6. Since then we get a lot of error messages saying:

" Beim Ausfuhren von Kernel auf dem Computer XXX ist folgendes Ereignis aufgetreten: Keine Verbindung zur Spamschutz-Cloud moglich, Spamschutz ist nicht vollstandig funktionsfahig"

This message shows up 5 or 6 times a day - I wonder if this is normal?

Please check if a firewall allows ESET Mail Security to connect to the Antispam servers listed at https://support.eset.com/kb332/#antispam.

Thank you Marcos, I was not aware of this.

Unfortunately after adding the exception to our firewall the error still occurs. Any idea why?
