ARM - Public IP Address tcp/81 not open

Hello Support

I have setup in ARM the following

1 x Azure Load Balancer (Internet Facing with public ip address)

1 x Availability Group

2 x haproxy servers

3 x www servers

I have multiple sites setup

Site_1 - 0.0.0.0:80

Site_2 - 0.0.0.0:8080

Site_3 - 0.0.0.0:81

Site_4 - 0.0.0.0:15672

Sites_1 & _2 work through I can browse these publicly and everything looks correct

Now if I try to telnet to Sites_1:80 & _2:8080, on the public ip address this works fine

If I try to telnet to Site_3:81 - it times out on the public ip address

and the same for site_4:15672 and the same for this aswell.

from the individual haproxy ip address I can browse to the site on port 81 but not on the public ip address

So i've proved its not an haproxy thing and it works locally and also not a NSG issue either

Its just the public ip address

Can you please advise

regards

James
