Can't Connect New Miner's To Account

I thought I was losing it. Have been trying to set up three more miners; 2-S9i's and 1-L3+, but no matter what I do, they won't associate to my account and start mining. Even had a co-mining friend of mine check my work and he says it all looks good.
Tried sending a helpdesk inquiry, but nobody has gotten back to me. At this point all I can conclude is it's something with my account.
Anyone else having this issue lately?
