VPN client does not connect to OpenVPN server (error).
-
Hi,
I can't connect to my OpenVPN server. It should work with the current configuration because I have done it before in the far past and it wasn't that hard, unless they changed something overtime.
This is the error I get, I think this is a general error, which basically means it can be anything. I double checked the basic settings, gone through the manual over and over again. It is quite possible I might have overseen something. I am using a dynamic host name (no-ip) instead of an Interface address (Export key tab).
It is worth to mention and I included it in another screenshot, the OpenVPN server does not seem to be running, the green start button does not respond. As far as I can remember, this should be on prior connecting.
Can you guys help me out? Or can someone give me a lead where to start?
Other screenshots can be provided if necessary, but please God no,...

As the server is not running it's naturally clear that the client can't connect.
The OpenVPN log on the server should provide the reason for the server cannot start.

Hmm, indeed, apparently the error was related to a wrong combination of a network statement and its subnet mask. The tunnel network does not accept /16 so I used /24. Very odd I must say the least. 172.16.1.0/16 is valid one right and therefore should work.
Thank you

(a) There is no reason to use a
/16
for a VPN tunnel network, especially not with topology subnet. You are not going to get 65,500+ clients connected to a single OpenVPN server.(b)
172.16.1.0/16
is not a valid network specification,172.16.0.0/16
is where that/16
starts, which is the cause of that error. -
Hmm, yes indeed.
