The problem is not "not having a password"
I run fly-pool with no password. no problem. I have the same settings as tropulus (aswell as 3 workers).
But how did you determine the Worker name?
Tropulus did without WorkerName..say i have two rigs with same specs, i won't be able to know which one is active or down..
Thanks btw..
This is what i have in mine
zm --server us1-zcash.flypool.org --port 3333 --user t1SHwi4DJoaCpvPfFmaX8vx7orJo8xufUTL.BigT
The worker names can be anything you want. so long as its just numbers and letters, no special characters or spaces.
