Http minipot is blocking nginx http

I’m using Turris Omnia (TOS 5.2.2) with slightly modified config of the web administration (re)foris/LUCi over lighthttpd. Default ports of lighthttpd are relocated to upper location and instead of them there is installed nginx on ports 80, 443 serving as reverse http(s) proxy access for IPv4 only clients from WAN. All works OK for https (443) but there is other server reply for http request instead of nginx - see bellow:

wget --verbose --server-response -4

Navazuje se spojení s (|xx.xx.xx.xx|:80… spojeno.

Both ports are enabled in firewall and nginx is listening on both 80, 443 ports of wan interface. Same problem I have with (Let’s encrypt) validation request, when I switch off nginx. Do you know how to reclaim sentinel-miniput service to release http redirection in firewall of the IPv4 WAN interface?

I have the same question - I need HTTP port available on WAN for Let’s Encrypt certificate renewal. Is there a way, to (temporarily) disable the redirection of http port on WAN to Sentinel minipod?

I recommend using the procedure from the manual here
