Forwarding port 80 [Solved: provider is blocking it]

UPDATE: provider is indeed blocking port 80. Bastards.

I am currently stumped. I have forwarded 2 of my wan ports to my internal ip (80 and 443), They are both forwarded using common syntax rules, that is:

config redirect
    option target 'DNAT'
    option src 'wan'
    option dest 'lan'
    option proto 'tcp'
    option src_dport '80'
    option dest_ip '192.168.1.10'
    option dest_port '80'
    option name 'Nextcloud HTTP'

config redirect
    option target 'DNAT'
    option src 'wan'
    option dest 'lan'
    option proto 'tcp'
    option src_dport '443'
    option dest_ip '192.168.1.10'
    option dest_port '443'
    option name 'Nextcloud HTTPS'

Yet nmap reports port 80 as filtered, while port 443 is perfectly accessible externally, also both ports are open from lan, so I know who to blame (well unless my provider is blocking some ports in it’s eternal wisdom). Anyway I can properly diagnose and solve this issue? Because I need that 80 port properly forwarded.

The fact that the provider is blocking port 80 is strongly non-standard. So much I can’t believe it.
Rather I believe they can block other ports for email client

First I acted with the provider.

Give me your external IP address for test

My provider charges extra for static IP address and to motivate people to pay more it closes popular ports (depending on the network segment , FTP, HTTP, HTTPS and others), so when static ip service is bought it unlocks the ports.
I was rather put out, when I found about it, because I spent a lot of time trying to solve the issue. At least I know what is happening now.
Still, you are welcome to try, I’ll PM you.

@Perpetual What is your place of residence and what is the name of your provider? I have a similar issue. I can open my https port with no problem but port 80 just won’t open. I am trying to reach my ISP at the moment and ask them about it.
