FYI when using stratum proxy
2012-11-27 21:57:58,967 INFO proxy jobs.extranonce2_padding # Extranonce size mismatch. Please report this error to pool operator!
No problems when using getworks.
Which miner are you using?
CGminer 2.9.5
https://bitcointalk.org/index.php?topic=28402.0 works fine with Stratum for me.
This message comes from the slush's stratum proxy..
https://github.com/slush0/stratum-mining-proxyI was using cgminer 2.9.5 with the --fix-protocol parameter to connect to slush's stratum proxy, then I just pointed the proxy to btcoxygen.com.
I just tried to connect to my own pool with slush's proxy and everything worked well.
Just try again and see if you face the same error.
