This is not correct. The ‘connection is not private’ warning screen does not appear if you are using HTTP, as security certificates do not exist for HTTP connections.
The problem in this case is the DevForum redirecting individuals in Asia to
forum.robloxdev.cn when they are not in China.
I was not able to reproduce this issue when using a VPN within Taiwan, South Korea, or Japan. While the issue also couldn’t be reproduced using a Hong Kong VPN, it did redirect me (302) to Tencent.
