I couldn't log in at https://claimfreecoins.io/ for one week.

I've experienced it before, at that time I only let it go for 24 hours because I thought, maybe I had passed the claim limit and after 24 hours I could make a claim back.

For this time I do the same thing, let it for 24 hours, but it didn't work. However, this time I even left it for a week and I still can't claim. then I tried to clear my browser history (including cookies and cache), then after 12 hours I tried to login again and this time it worked.

My bitcoin address is not only problematic on claimfreecoins.io, but also on coinbid.ro and so far I have not found a solution
