This is my forum’s [link](https://discussions.tricklehub.com/). Is that because of Discourse settings’ problem? [EC2 Reachability Test](http://ec2-reachability.amazonaws.com/) website show every region is able to reach directly. And I think it isn’t because of the GFW, because I can visit [www.tricklehub.com](http://www.tricklehub.com) directly.

That would be my guess too.

If I were to set up Discourse for people in China I’d use Alibaba.

Which was your guess? The Fire Wall. Discourse settings’ problem or the EC2 conecting problem?

Solved, the reason is:  
Because of when I reboot EC2 Instance, it will reallocation IPv4 Address automatically. Unfortunately, this time reallocated IP Address was banned by the GFW before it reallocated to .

Solution:  
Allocate a new Elastic IP to Instances.
