My miners work fine for a pool. But when I try to run solo I get either a very, very slow hash rate and super high error rate(s), or the miners may also refuse to connect to the machine running bitcoin-qt/bitcoind and also may incorrectly report connections as being alive or dead.
I have tried upgrading cgminer to the most recent version, to no avail. Often, cgminer quits after a few minutes.
here is my cgminer command line (<> indicate substitutions to protect the innocent):
--bitmain-options 115200:32:8:18:225:0882 -o http://192.168.0.2:8332 -O
here is my bitcoin-qt/bitcoind command line:
-datadir=/home/
The verbose flag did not seem to give any more info, I can find an open port :8332 on the bitcoind machine and netstat will report "ESTABLISHED" then "CLOSE_WAIT".
Any suggestions on how to debug the rpc connection or cgminer would be greatly appreciated. I may have no hair left soon.
