Have problem with coova chilli listen https port 443

[htnghia90]

Hi everyone,
When I send request form https to http 10.1.0.1:3990. I got message
was loaded over HTTPS, but requested an insecure script 'http://10.1.0.1:3990/json/status?callback=jQuery31104840072604399721_1539138359703&_=1539138359704'. This request has been blocked; the content must be served over HTTPS.

I installed openssl-util in tp link c7 openwrt
I follow this link for create certificate key with IP.1 = 192.168.12.1
https://openwrt.org/docs/guide-user/luci/getting-rid-of-luci-https-certificate-warnings

I already set config in /etc/config/chilli/
option redirssl 'on'
option uamuissl 'on'
option sslkeyfile '/etc/ssl/uhttp.crt'
option sslcertfile '/etc/ssl/uhttp.key'

Anyone know this issue, help me please
