Hey folks.  

im trying to switch from nanopool to slushpool.

Nothing is working with slushpool.  

error im getting:
connected to zec.slushpool.com:4444 failed

I am thinking it is slushpool issue, but want to touch a feather here in case i missed something.

I have tried the following:

miner --server zec.slushpool.com --user USERNAME.workername1 --pass z --port 4444

miner --server zec.slushpool.com --user WALLET.workername1 --pass z --port 4444

miner --server us.zec.slushpool.com --user USERNAME.workername1 --pass z --port 4444

miner --server eu.zec.slushpool.com --user WALLET.workername1 --pass z --port 4444

miner --server us1.zec.slushpool.com --user USERNAME.workername1 --pass z --port 4444

miner --server eu1.zec.slushpool.com --user WALLET.workername1 --pass z --port 4444

this is the only help they offer:

Getting Started - Zcash
1. Create an account with Slush Pool

    Sign-up and wait for a confirmation email.
    Login to your account.

2. Configure Your Device

The login credentials for your miner look like this:

URL: stratum+tcp://zec.slushpool.com:4444
userID: userName.workerName

    Please note that we do not support Zcash addresses directly in the command. Use your Slush Pool userName instead.
    workerName is optional, if you do not provide any it's fine. Our system will automatically create auto worker for you.


The servers can be chosen from the following list based on your geographical location:
Servers Location    Address
USA, east coast    stratum+tcp://us-east.zec.slushpool.com:4444
Europe    stratum+tcp://eu.zec.slushpool.com:4444
