Infinite login loop in China

(@gabsoftware)

Hi there,

I’d like to report a problem I have since a long time with WordPress in China.

Whenever I don’t use a VPN, I cannot login to any WordPress blog. The login page is loaded again and again. It seems that it is not possible to login to WordPress with the “China Telecom” ISP (also known as Chinanet). As soon as I connect with a VPN, or login from outside China, there are no problems.

What changes between China and outside China is that the request GET /wp-admin/ HTTP/1.1 returns a HTTP/1.1 302 Moved Temporarily instead of a HTTP/1.1 200 OK, also the following header is set Location: http://www.example.com/wp-login.php?redirect_to=http%3A%2F%2Fwww.example.com%2Fwp-admin%2F&reauth=1 and then it loads wp-login.php again instead of loading /wp-admin.

Here is a typical login request from China:

Could someone in the WordPress team find a solution and fix this problem? It would be awesome for Chinese users.

All the best,
