There is not just issue on logging in, but also in claiming. I can log in, but I can't claim cause it says that:

"An error occurred: Please note that someone with this IP already claimed the faucet!"

I just use this faucet from household, and my account is the unique one using it.
Just in case I resync'ed the router to get a new IP from ISP, but the problem is still there, it claims that another "account" has already claimed from my current IP which obviously has not happened.

Hoping you fix this problem ASAP.

Cheers.
