Problem with Public Load Balancer

Hi all

I created a public load balancer for 2 VMs and have NAT rules working fine for RDP but the load balancer not working for HTTP port 80

TCP port 80 probe created

Load balancing rule created for TCP/80 to Backend pool using TCP probe

Backend pool with the 2 VMs

Inbound NAT rules for RDP - both working connecting to load balancer using load balancer DNS name and port number

loadbalancername.northeurope.cloudapp.azure.com:3441

loadbalancername.northeurope.cloudapp.azure.com:3442

I can browse web page on each VM internally from each other and have created the inbound security rules for port 80 on each VM Network Security group.

I just can't access the site and struggling to find any issues so would welcome any troubleshooting tips on the load balancer. The fact the NAT rules work suggests that the issues lies with probe, back end pool or inbound security rule but can't see any problem.

Many Thanks

Andy
