For the last couple of days the site is kind of shaky, sometimes I have to reload the page up to three times to click the faucet successfully.
The WOF mostly returns the "500 INTERNAL SERVER ERROR"-page or the small "ERROR for site owner: Invalid site key"-message, so clicking the WOF takes a lot of attempts to succeed.
I noticed it too. Don't have problems with WOF spins, but faucet rolls doesn't always work properly. After I click roll, these numbers rolls endlessly and after I reload page, I get error from Cloudflare.
