I just saw this and had never been touched but a written warning that my IP is already in use, while I have not tried it with my static IP
I tried and get the same message - must be a fault in the faucet or something else
I also look at my browser to get the same warning and I think the owner of the site this faucet can explain the problem on its website
Guys, I'm sorry, looks like it was redis problem. I've reset the database, so now everything has to work as designed.

Glad to hear your explanation, at least I am just testing the site and report the error in your site, it may be useful to existing communities in this thread
