Hi,
unfortunately I couldn't find any solution to my problem with the help of already existing threads yet. I configured a Ubuntu 22.04 VM as a OpenVPN TAP VPN server similar to this guide: viewtopic.php?t=30633
The first connection from a Windows 10 client with the OpenVPN GUI software usually works without a problem but when trying to reconnect from the same client or connect from another one, it gets stuck at:

Code: Select all

MANAGEMENT: >STATE:1690392555,WAIT,,,,,, 
UDP WRITE [42] to [AF_INET]IP:1194: P_CONTROL_HARD_RESET_CLIENT_V2 kid=0 pid=[ #1 ] [ ] pid=0 DATA len=0
UDP WRITE [42] to [AF_INET]IP:1194: P_CONTROL_HARD_RESET_CLIENT_V2 kid=0 pid=[ #2 ] [ ] pid=0 DATA len=0

The problem persists until I restart the server with

Code: Select all

service openvpn restart

While the client fails to reconnect, the server log doesn't show anything but this:

Code: Select all

2023-07-26 19:39:35 us=473850 MULTI: REAP range 144 -> 160

I already tried changing the protocol from udp to tcp, but it didn't help...

Server config

port 1194
proto udp
dev tap
ca ca.crt
cert server.crt
key server.key
dh dh2048.pem
topology subnet

Client config

Hopefully someone can help me
