Connection error with Unmineable Kawpow pool

I've been trying to connect my rig to Unmineable to see the rentability of mining ETH from kawpow algorithm.

It's not the first time I use Unmineable but I just can't get it to work. When I launch the t-rex .bat file, I got a bad address error message and that's it.

t-rex.exe -a kawpow -o stratum+tcp://kp.unmineable.com:3333 -u ETH:Wallet_Address.worker -p x –gpu-report-interval 500

Anyone can tell what I'm doing wrong ?

Thanks in advance 🙂
