Many home ISPs block port 80 and 25. You should be able to Google that and confirm. If that’s the case you’ll have to use a different method.

ISP said that it does not block port 80

Try something like www.webpagetest.org or any other “proxy” service to confirm for youself if it is publicly accessible.

This is the answer. Pretty much every ISP blocks 80 They say it is because worms use it blah blah but it is exactly what you think. They don’t want you running a web server. You’re probably going to have to do the DNS challenge instead.
