Turns out the guy I rented from had his machines off..
Had me going crazy for a hot second.
All refunded and good.
Hopefully for the better and I smash a block.
Thanks, for some reason not working for me.
try port 4334 instead
I have successfully used MRR to rent hashrate here with the following config:
Pool Host:Port=solo.ckpool.org:4334
Workername=YourBTCWalletAddress.workername
Password=x [or whatever, it doesn't matter but above I'm using Hi Diff Port 4334 not 3333]
Good luck!
