Hello,
We're working to resolve an SSL certificate mismatch for Challonge right now. We started using
CloudFlare yesterday, and their docs assured us that this wouldn't happen...but here we are. I have an open ticket with them, and if it's not resolved today, I'll revert everything back — I would do it right now, but the name server change takes a while to propagate.
In the meantime, check your API requests, and if they're not going through, you'll need to allow certificate mismatches until we resolve the issue.
Sorry for the inconvenience,
Dave
