client connecting but cannot reconnect

Post by dlugasny » Sun May 02, 2021 10:32 am

Hi,

maybe some one will be able to help me.

I have VPN Server which is working. I`m able to establish one connection , but when I try to reconnect my client (Android or Windows) then client returning that error:
Sun May 02 12:29:24 2021 Socket Buffers: R=[65536->65536] S=[65536->65536]
Sun May 02 12:29:24 2021 UDP link local: (not bound)
Sun May 02 12:29:24 2021 UDP link remote: [AF_INET]46.41.137.80:1194
Sun May 02 12:29:24 2021 MANAGEMENT: >STATE:1619951364,WAIT,,,,,,
After server restart, client will be able to reconnect. Where is the problem in my configuration ?
Which parameter is missing ?

My server.conf:
port 1194
proto udp
dev tun
user nobody
group nogroup
keepalive 10 120

Hi,

I had a problem with reconnection last week. I only could reconnect if I "disconnect" first and then "connect" but couldnt "reconnect" directly.

I fixed it with "lport 0" in the client configuration.

Regards, Adrian.

You need --nobind instead.
