It only firewalls on FAILED LOGIN ATTEMPTS... so... either you failed logging in one too many times, or you somehow pissed cloudflare off and they forced a captcha on you. The firewall applied on failed logins automatically clears after a short period.
Thanks for the reply... to be clear I wasn't logging into the Havelock website nor was my application.. it was only collecting public ticker information from the JSON api calls.
The cloud host blocked my IP address without any recourse.. no captcha.. no explanation, no place to send emails queries etc.. nothing.. just a page saying Your IP address has been blocked buy Havelock.
anyways Long story short and for anyone else involved in developing bots for this site. the block was lifted several days (maybe a week) later...
I'll have another look at my code and try to reduce the IP traffic even further.
cheers.
