Either open 3main and edit the 2 lines and add :$XMR_PORT in this section :
if [ $plusCPU == "YES" ] && [ $AUTO_START_MINER == "YES" ]
guake -n $HCD -r plusCPU -e "$HCD -a cryptonight -o stratum+tcp://$XMR_POOL:$XMR_PORT -u $XMRADDR -p x -t $threadCOUNT"
else
screen -dmS plusCPU $HCD -a cryptonight -o stratum+tcp://$XMR_POOL:$XMR_PORT -u $XMRADDR -p x -t $threadCOUNT
Or run the update script again to fix it for you
I edited those 2 lines in 3main and changed 1bash back to the new way with port on a separate line. The XMR miner now connects to the pool. However, the miner still exits within 20 seconds of starting for some reason. The screen window closes immediately when this happens.
