Configure NginxProxyManager to forward two ports for the same domainname to the same host

Job ID: 33512846

Budget: €30 – €250 EUR

We are using the Nginx Proxy Manager.

Now we need to forward two different incoming ports e.g. 1234 and 1235 for the same domain name to the same ports to the same host. But when I try to add the domain name a second time for the second port, I get the error, that the domain name is already in use.

Who can tell me, how to configure this with the Nginx Proxy Manager in a proper manner?
We will collaborate on this by using TeamViewer. You have to have a clear idea, what to do.
