The OpenVPN server on mikrotik falls off. Why?

Question

linux

On Mikrotik, an OpenVPN server is running, to which you can connect only once. After stopping the client, reconnection does not occur. in client log

TCP: connect to [AF_INET]xxx.xxx.xxx.xxx:1194 failed, will try again in 5 seconds: Connection refused

It is possible to connect only after restarting the OVPN server.
What could be the problem?

dev tun
proto tcp
remote xxx.xxx.xxx.xxx 1194 
client
resolv-retry infinite

<cert>
</cert>
nobind

keepalive 10 120
route-delay 2
