[OK] read UDPv4 [ECONNREFUSED]: Connection refused (code=111

[zeycron]

Hello,

my installation (bridged) is ok, but when my users are deconnected this message appears in my logs (server side) during few minutes :
read UDPv4 [ECONNREFUSED]: Connection refused (code=111)

is it normal?

Example (server side) after a deconnection of user-1 :

Jun 3 12:47:46 server ovpn-server[15148]: user-1/XX.XX.XX.XX:60900 MULTI: Learn: 3e:d2:21:XX:XX:XX -> user-1/XX.XX.XX.XX:60900

it's enorme??

my server.conf is :

PS : the last ligne is to check if common_name = username

thanks!

when a (UDP) client disconnects the server is not aware of this and will try to contact the client again. Only after a certain interval will the server give up and remove the client from its list of known connections. The messages you are seeing are caused by this.
Add

Code: Select all

push "explicit-exit-notify 3"

to the server config; this instructs the clients to "sign off" when they disconnect.
