Hi,

Connecting to azure with Nginx Proxy Manager from internet with https trying to reach the Nginx server that is hosted in on-prem which is an directly connected ExpresssRoute between my azure and on-prem environment. So far i can connect to Azure but cannot hop to my on-prem environment while the network was learned within bgp.

Anyone familiar with such a configuration? I really appreciate your help.

    Hi,

    if you can reach Azure but not hop to on-prem try to do a quick checks like that

    Ensure the on-prem network routes are properly advertised and learned in Azure via BGP.

    check if any Network Security Groups (NSGs) or firewalls are blocking traffic between Azure and on-prem.

    Verify Nginx Proxy Manager is correctly set up to forward traffic to the on-prem server.

    Double-check DNS resolution and SSL certificates to ensure they’re valid for the on-prem endpoint.

    If all looks good, it might be worth testing with a simpler setup (e.g., direct HTTP) to isolate the issue. like that.
