Since yesterday I've been mining on Prohashing again. However, I'm seeing very low payout rates and my reported hashrate is quite erratic

This is for 4 Antminer L3+ miners. Connected workers is also fluctuating a lot. More often then not I'm not seeing any connected worker, and my hashrate is 0. If I restart one of the miners it'll show up, and disappear after a while. Is this expected behavior of the site, or are my miners misconfigured?
Right now, to eliminate some dumbass typo I cleared the password box on all of them, but this doesn't seem to have made a difference.
