Can't receive any UDP packet
SummaryI am using wireguard VPN, without any changes, my instance suddenly can't receive any udp packets
I have been using wireguard to secure communications between my instances
Some of my instance located in Japan, some located in China
I have permit firewall rules on subnet and instance, my vpn has been working fine for a month.
Today, Estimated time should around GMT-8 12:15, my vpn lost connections
After troubleshooting, I found all my nodes lost connection to Oracle instance
It seems that my instance can't receive any UDP packets...
May be some security involved, Wish someone could have a look on it.
