Port forwarding not working at port 80 on RT-AC68U !!!!

[SugarRider]

Hi guys, I have a TR-AC68U with firmware 3.0.0.4.384_21140.
In my LAN I have a web server that publishes on port 80.
I would like to publish to WAN on the same port 80, but it does not work.
when I change the external port to 8080 it works without problems.
I test the external port through the site: https://www.yougetsignal.com/tools/open-ports/, which informs that port 80 is closed.
in the forwarding configuration I have already put the local port and also left it clean. did not work in any of the ways.
I have already turn Firewall off and on, I already turned on and off Upnp, I already tried the server in DMZ, and it also did not work, but I do not want it on DMZ.
I even installed MERLIN 384.60 and then went back to ASUSWRT. Nothing worked.
I'm out of ideas, please help.

Some ISP had port 80 blocked, check if your ISP do it
