I havent tried the API access for S9. I gave it a try on one miner to test it and now the miner is showing Disconnected in the program. The miner is working good on the pool. Updated to 2.4

I tried different combinaisons of rules, it always says OK in the list but I can't get the miner reconnected to the program.

W:192.168.2.160
W:192.168.2.160,W:127.0.0.1
W:127.0.0.1/32
w:192.168.2.160
etc

What I'm doing wrong?
