can you show me your command line? I never had problem entering claymore commands? maybe you put two spaces between commands? or two --? it has to be some minor thing that you don't see.
RIG 1 config is
-zpool stratum+ssl://equihash.hk.nicehash.com:33357
-zwal 12jb2ShuwhqbaxcEeU5McLwHQiSjzibb2N.290
-zpsw x
-a 0
-allpools 0
-i 7
-ftime 1
-di 01
-tt 50
-ttli 85
-tstop 90
-fanmax 90
-fanmin 60
-cclock 1000,1000
-mclock 1400,1400
-mport 3334
-wd 1
-r 0
-colors 0
and Rig2 is
-zpool stratum+ssl://equihash.hk.nicehash.com:33357
-zwal 12jb2ShuwhqbaxcEeU5McLwHQiSjzibb2N.7990
-zpsw x
-allpools 1
-a 0
-i 7
-ftime 1
-di 01234
-tt 75
-ttli 90
-tstop 95
-fanmax 95,95,85,95,95
-fanmin 80,80,75,80,80
-cclock 850
-mclock 1400
-colors 0
-wd 1
-r 0
-mport 3334
i enter newline all option and all rig are after firewall then it's must not have same port.
change mport to 3333 or delete this line. It not correct. The client connect to miner with 3333 port.
