I have 123 if your so curious... Doesn't change a thing...

@didjaydisteele
What exactly is your point? It is a litecoin mining pool...

@Lacan82
It doesn't matter what you have for pass since that pool doesn't use passwords...
Doesn't work...

I am getting this error using cudaMiner:
http://shrani.si/f/1J/zA/18PFvNsm/11.jpg
http://shrani.si/f/1N/jk/3m4BYXU4/2.jpg

I tried different pools, different instructions, but it seems it just won't connect to the server. And I am sure it's not an issue with my net/port-forwarding/firewall since all my other miners work without a problem...
Anyone has any idea what might be causing this?

It's not about the instructions, it seems it just can't connect to the server.
My net connection is o.k. and ports are opened cause I can easilly connect to the same pool with other miners...

>>> Example command line options, advanced use <<<

cudaminer.exe -H 1 -d 0,1,2 -i 1,0,0 -l auto,F27x3,K28x4 -C 0,2,1
-o stratum+tcp://coinotron.com:3334 -O workername:password

This is an example from the readme file. The code is based on cpuminer which works fine for me on P2Pool, so the pool itself shouldn't be the problem.

...And I can't use PM's yet, since I am new here...

Nah, doesn't work...

Command: stratum+tcp://server2.p2pool.org:9327 -O USER:PASS -i 1

The pool info for P2Pool Litecoin mining pool is surely correct as I can run cpuminer (https://bitcointalk.org/index.php?topic=55038.0) without any problems. So it has to be something with the cudaMiner, or some dependancy it has...

Thanks for the advice. I still hope for an answer from someone with a good knowledge about this particular miner and this error.

Such a usefull answer...

I tested it on a Litecoin P2Pool aswell and it gives me exactly the same error:

Well yeah, I though about that, hehe... however I followed a guide for bitcoin mining...
Anyways, which miner would be the best for nVidia cards for Bitcoin mining?

I am getting this error using cudaMiner:
http://shrani.si/f/1p/bT/3bUebnOo/1.jpg

Using this line as instruction: cudaminer -o eu-stratum.btcguild.com:3333 -O user:pass -i 1
The miner also doesn't auto-tune itself...

Anyone knows where the problem is?
