Results vary across kmao.co: of 3 URLs tested, 1 is blocked and 2 load normally. The Great Firewall blocks the connection outright. 60 tests have been run under this domain since 2018-05-09, the most recent on 2026-09-14.
The two are filtered by different means — an unencrypted request by the address and keywords it carries in the clear, an encrypted one by the server name in its TLS handshake — so one working while the other does not is normal.

Plain HTTP and HTTPS differ here: http://kmao.co is blocked, https://kmao.co is not blocked. The two are filtered by different means — an unencrypted request by the address and keywords it carries in the clear, an encrypted one by the server name in its TLS handshake — so one working while the other does not is normal.
A VPN or another circumvention tool routes the request outside mainland China, past the filtering that blocks kmao.co. GreatFire runs GreatFire VPN; the Analyzer also tests the domains of many VPN and proxy providers, so you can check whether one is reachable before relying on it.
