TUN Write Error. Once Again!

I have hit a wall. For the life of me I cannot seem to get openvpn working. The clients are able to connect but I am plagued with
Code: Select all
2013-09-09 15:46:52 TUN write error: cannot identify IP version for prefix
2013-09-09 15:47:02 TUN write error: cannot identify IP version for prefix
2013-09-09 15:47:42 Session invalidated
2013-09-09 15:47:42 Client terminated, restarting in 2...
2013-09-09 15:47:44 EVENT: RECONNECTING
The clients seem to connect fine, but no traffic is exchanged. I've googled far and wide and came up short.
Here are my configs

I found another article on the forum on the same exact topic but it did not help me...
So if anyone could help me I'd be very gracious!
Thank you in advance, Randoslap
P.S. Running Ubuntu Server 12.10 x86_64

Sorry about lack of information. Dumb Newbie here.
Anyways, I'll get those logs and clean up the config files!

Whoops! The Lack of authentication is a simple copying over to forum error.
Code: Select all
ca ca.crt
cert (RealName).crt
key (RealName).key
That's a me typing error, It really does have authentication, sorry about that.
Also, my issue seems not to be a Authentication error as everything in that respect
seems to work.
I have a feeling that i've gotten something wrong when it comes the network settings in the config.
