Can someone help me please? I was mining on this site, http://www.atomicapool.com/mining_urls, with this background in bfgminer v5.4.2:
bfgminer.exe --scrypt -o stratum + tcp: //pool.atomicapool.com: 3029 / # xnsub -u FAPshBo53xoRY6RW5Wm4Lc9qzwPnmfpzDq -px -d gridseed -S gridseed: all --set-device gridseed: clock = 850, chips = 40
It closed for a few days and now the same command does not work.
I moved to this one and nothing.
bfgminer.exe --scrypt -o pool.atomicapool.com:3029/#xnsub -u FAPshBo53xoRY6RW5Wm4Lc9qzwPnmfpzDq -p x -d gridseed -S gridseed: all --set-device gridseed: clock = 850, chips = 40
In both cases this was the response of bfg:

No servers were found that could be used to get work from.

Please check the details from the list below of the serve.

Most likely you have input the wrong URL, forgotten to add a port, or have not set up workers
