Users on enterprise networks (specifically some schools in Japan, Hong Kong and Sweden) are experiencing timeouts when accessing the site through Cloudflare proxy. They see an acknowledgement of the DNS request, but https requests are not acknowledged. When proxy is switched off, their access is restored.
What steps have you taken to resolve the issue?
When the proxy is switched off for www., the users can access the site normally.
They have not provided a screenshot, but have described a timeout after about ten minutes. They are only experiencing this issue when accessing the site via their school network; if they use a mobile phone, they have normal access.
They have confirmed that there are no policies on their network that should be blocking access.
