can't connect as vpn client linux

[toor]

Hi,

I have successfully created SoftEther VPN server @ ubuntu 14.04 LTS x64, I'm able to make connection with android device - works like a charm!
Version 4.20 Build 9608 (English)

Problem occurs when I try to connect to it with vpnclient for linux.
Client is ubuntu 16.04 LTS x64.
First I do:
sudo ./vpnclient start
SoftEther VPN Client service has been already started.
Run the "vpnclient stop" command to stop this service.

Then:
sudo ./vpncmd
2. Management of VPN Client
I get error:
Error occurred. (Error code: 1)
Connection to the server failed. Check network connection and make sure that address and port number of destination server are correct.

And than I tried few combinations:
ip_address
ip_address:port
hostname
hostname:port
DDNShostname
DDNShostname:port

Tried all ports (443, 992, 1194, 5555).

Next I tried to:
restart server
restart vpnclient
checked using telnet if I can connect to all ports - yep! that also works.
At the end I tried and installed SoftEther VPN server at different machine/location/ip - result is the same - Android connected but no vpn client linux connection.

I'm attaching server configuration without passwords and IPs.
Here's my VPN server ifconfig without ip address:
eth0 Link encap:Ethernet HWaddr 52:54:00:55:a7:b9

Any suggestions please?

So I created another server, this time with Ubuntu 14.04 LTS and I used the newest VPN server and client: Ver 4.21, Build 9613, beta

And I have exactly same situation:
Error occurred. (Error code: 1)
Connection to the server failed. Check network connection and make sure that address and port number of destination server are correct.

This time I'm trying from another 16.04 LTS client computer.
Telnet says that all ports are open and connectible.

Server log shows only something like this (I cleared my IP and hostname and purpose) :
2016-07-04 18:18:44.646 On the TCP Listener (Port 5555), a Client (IP address , Host name "", Port number 36172) has connected.
2016-07-04 18:18:44.646 For the client (IP address: , host name: "", port number: 36172), connection "CID-6" has been created.
2016-07-04 18:19:34.048 Connection "CID-6" has been terminated.
2016-07-04 18:19:34.048 The connection with the client (IP address , Port number 36172) has been disconnected.

Client's log shows only initiation information of "vpnclient start", not a word about lost connections.

Either way something broken with client or I'm doing something wrong - what would that be?

Strace shows this:

I think it's about this to be exact:
-1 EAGAIN (Resource temporarily unavailable)

any suggestions?

So, I would say this was a problem:

Not to fight with static routing easier solution is to enable OpenVPN Clone function and you can easily connect from linux with native OpenVPN client :)

Cheers!

Hi there, i would really suggest to stick with SE client for linux instead of OpenVPN client, check again you setup and configuration and may be this time you can get more help, trust me on that point (:.



Good luck (:

First of all, you should connect to VPN client to manage VPN client.
I think you try to connect to server IP address with VPN client manager.
