Standard Port Forwarding not working

[Bondy86]

EE Full Gig broadband using a EE Smart Hub Wifi 7 router
Followed the User Guide and a YouTube video but CANNOT get port forwarding to work.

I can 100% access those devices via my LAN on those ports and they work 100%
Cannot access them via my WAN IP address on those ports.
PortChecker shows the ports are closed.

However when I put the server into a DMZ (DO NOT RECOMMEND) I can then access the ports from my WAN which must mean the Router/Firewall is not working correctly.

Please can someone recommend a fix for me.
Kind regards,

When I first configured port forwarding i go many chop errors.  Couldn't create needeed static ip, couldn't save,  multiple entries,  it was ridiculous.  Eventually after several attempts and a factory reset i finally got both ports open,  although they were closed until reboot. Despite them showing open, letsencrypt still failed as logs showed it couldn't send to port 80 despite it working outward. Support (2 hours) had no idea, and they insisted on engineer coming on Friday. When I tried renewing certs on Friday morning to show engineer errors,  I suddenly worked out of the blue. Engineer they sent was broadband engineer and knew nothing about reverse proxies.

Silly question but you have rebooted?  Maybe pain of factory reset may work?

Other than that, I'm stumped.  Don't understand why 443 is open but 80 closed.

Rebooted multiple times to no effect. 

Did a factory reset and can now see the default nginx page so think that's resolved things. Thanks for your help & advice
