Hi Darren, thanks for responding. Yes, the event log listed 4 different IP addresses as sources. They are: 193.238.98.90; 185.94.111.1; 195.251.255.69; 203.178.148.19; and 206.117.25.90. I received multiple attacks from at least two of these IP addresses.

    I'm having a similar issue but the source is "fe80:0000:0000:0000:0214:f1ff:fee8:7fe2".  The attack is occurring multiple times a day.  How can I stop this?

      Hello birdm321

       

      Are there any Ip address that is in the logs that are causing the attacks?

        There are no traditional IP addresses listed as sources.  The only source in the log is the "fe80:0000:0000:0000:0214:f1ff:fee8:7fe2" I mentioned in my first post.
