Been having this issue since I downgraded from Pro to Free. My site will not connect using a major ISP in my country. It always show ERR_CONNECTION_REFUSED.
I have emailed CF on this, but still not resoled. After few digger, my server admin asked me to grey out A’ record and www’ record on CF DNS setting, which I did, and the issue was solved immediately. But I want all my traffic to pass through CF for security and other reasons, but turning them on again, result in the above error. But everything was working OK before I downgraded.
My server admin thinks the government of my country or my ISP is blocking certain IP address in my region. Because, using same ISP with a VPS load the site without any issue.
Please how do I fix this. Thanks
