CloudFlare could not access my server from Tokyo & Singapore


Today I found that CloudFlare route my request to CloudFlare Tokyo and it could not connect to my server. I have try to use VM from other locations like US and CA then can access to my websites.

I have already whitelist all CloudFlare IPs from so why Tokyo could not access to my web-server?

Does anyone have the same issue? What exactly Tokyo IP/CIDR?

Thanks & Best Regards,
