Stratum Proxy Troubles

[Tonik546]

I've been searching around and I cant find any help with this...

I have two ASICMINER Block Erupter Cubes that I want to mine in the BTCGuild pool with. I am using Slush's mining proxy. In the batch file I have the commands...

mining_proxy.exe -o stratum.btcguild.com -p 3333

Earlier today I got it running, each cube cranking out around 35 GH/s. After about four hours I started getting this error in the stratum proxy. https://i.imgur.com/BszjyDO.jpg

If I restart the proxy with the batch file it will work for maybe 5 seconds then come up with these errors again.

I feel like something must be wrong with my batch file because the stratum proxy works just fine to mine on slush's pool. Then again, it was working for four straight hours earlier.

Any help would be greatly appreciated.

EDIT: I have used several commands in the batch file including....

mining_proxy.exe -o eu-stratum.btcguild.com -p 3333
mining_proxy.exe -o stratum.btcguild.com -p 3333 -gp 8332
mining_proxy.exe -o stratum+tcp://stratum.btcguild.com -p 3333
mining_proxy.exe -o stratum.btcguild.com -p 8332

... plus several more I cant think of off the top of my head.

Just an update...

It was suggested that I am unable to connect to the backend servers and my firewall could be the problem. I disabled my firewall to check and I still get the errors. Does anyone have any input on my problem?

Thanks!

Just in case anyone else has this problem, The issue was my username and worker input. For Slush's pool the input is <username>.<password> and for BTCGuild the input is <username>_<password>.

Once I changed the period to an underscore it worked fine.

Where did you enter in the username and password?
