prohashing link up L3+

can someone help i cant link up to prohashing with my antminer L3+ it took two weeks to get it to link up the first time and one day it just did but 3 days later it disconnected and have not been able to get it to link up since

It should be very easy to do.
Login to your L3+ by finding the IP address through your router.
Then it's as easy as copy pasting this into the boxes in Miner Configuration, General Settings:
URL: stratum+tcp://prohashing.com:3333
Worker: [whatever name]
Password: n= [whatever name] (or you can leave this blank).

That's all there is to it.
