[Openvpn-users] I set the local statement and I got Connection reset by peer (WSAECONNRESET) (fd=ec, code=10054)

Hello,
I added a virtual IP to my OpenVPN NIC as below:

...
enp0s3:1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 20.1.1.20  netmask 255.0.0.0  broadcast 20.255.255.255
        ether 08:00:27:ed:b4:7c  txqueuelen 1000  (Ethernet)
...

Then, I added the following line to my Server.conf file:

local 20.1.1.20


I did the following iptables rules:

IF_MAIN=enp0s3:1
IF_TUNNEL=tun20
YOUR_OPENVPN_SUBNET=10.10.0.0/16
iptables -I INPUT -p udp --dport 2000 -j ACCEPT
iptables -A FORWARD -i $IF_MAIN -o $IF_TUNNEL -m state --state ESTABLISHED,RELATED -j ACCEPT
iptables -A FORWARD -s $YOUR_OPENVPN_SUBNET -o $IF_MAIN -j ACCEPT
iptables -t nat -A POSTROUTING -s $YOUR_OPENVPN_SUBNET -o $IF_MAIN -j MASQUERADE
iptables -t nat -A POSTROUTING -s $YOUR_OPENVPN_SUBNET -j SNAT --to 20.1.1.20


But, the client can't connect to the OpenVPN server and showed me below error:

Sat Aug 12 11:10:24 2023 read UDPv4: Connection reset by peer (WSAECONNRESET) (fd=ec,code=10054)


How to solve it?


Thank you.
