Connection Timeout: NETWORK_EOF_ERROR

christiansam

Hi!

I have problems connecting with openvpn connect (ios) to my openvpn server. Before any crypto-stuff can get handled out, it breaks up with the following message:
---
logfile:
EVENT: CONNECTIONG
Tunnel Options: ...
Peer Info: ...
...
TCP recv EOF
Transport Error: Transport error on '<xxx>': NETWORK _EOF_ERROR
Client terminated, restarting in 2...
EVENT: RECONNECTING
----
Authentifcation mode is set to TLS with KEY CERT and CA generated by the easy-rsa utility. Except for changing auth-mode to something else I I tried (nearly) every possible mix of client-configration setting, without any success. My client-conf is based on sample-file, provided in windows openvpn package and works well with linux, windows and android openvpn clients.

Can't tell you exactly which version of the openvpn server I use, it is included in an alternative firmware for Linksys' WRT54G/GL routers, please see: http://tomatovpn.keithmoyer.com/

Best regards,
christian

Exactly thesame problem here!
Having a look on the server side it seems the connection never reach the server!

Dns resolution is fine (I see it in logs) but Connection Timeout: NETWORK_EOF_ERROR suddenly appears.

Are we missing something?

The same configuration works fine on Openvpn Connect on android.

Hate to add another "me to" reply, but I'm having the same issue.
The connection seems fine after first packet received, then the count down of the time since last packet received reaches <6, the connection resets.

- Using OpenVPN Connect Android Client 1.1.11 (build 44)
- Galaxy Nexus Android 4.2.2
- VPN protocol: Adaptive
- "Connection timeout": "continuously retry"
- Compression: off
- Seamless tunnel: on

Found out more about the cause of this: multiple logged in sessions. You cannot have more than one concurrent OpenVPN sessions.

I solved this problem by reducing the size of the key on the server to 128:

keysize 128

I made a reset to my primary router and
now the ddwrt have the same problem.
I don't know why, I didn't touch the ddwrt
configs at all. But I'm facing this problem.

When I use the internal connection (192.168.x.x)
I can connect to the server , but when I use
The Internet with my external ip, it doesn't work.
I have all configured: noip; port forward on my
primary router.... All worked fine before the router reset.

You fix the error just by adding the keysize
text on the server config, or you made
something else?
Did you creat other CRT or key file or something Else?

I've figured it out.

In my case it has nothing to do with keysize
My primary router was not properly configured.
It has several options for port forwarding.
And it wasn't correctly configured.
Work like a charm now.

Now all is Ok! I can confirm:
Only ONE session at the same time can be UP with the same cert.
