Server crash and have to do a full back and restore.
Since then I’ve been getting a lot of this messages
I have firewall and fail2ban enable
I normally blacklist the IP address but this time the x.x.x.x is the IP address of my server
I’m 100% certain I didn’t set up ext 30, 801 or test
I appreciate any info
