I have a question about which I am racking my brains. The following scenario. There is an application which displays a white page via the browser internally via a port and a path /keep-alive. Externally via the configured Nginx Proxy Manager the application is reachable via FQDN.

So Nginx Proxy Manager host has been set as a Docker. A proxy host has been added with the FQDN and the internal IP and a stream with the port . If I now access the port and /keep-alive from external I get

CANNOT GET keep-alive

And here I do not get further, how the parameters must look like which I must indicate in the Nginx Proxy Manager, so that Keep-Alive from extern (thus Internet over the FQDN with port) functions. I am still learning all this and would appreciate your help.

Thanks for your time
