Nginx proxy manager port forwarding

welcome to nginx proxy manager, I have set my nextcloud to connect via https, now I would like to set up an additional service, e.g. a torrent client. How to properly forward ports so that two services run on one domain? I will add that I forwarded the required ports on the router, i.e. 1212:1212

We are not the support forum for the nginx proxy manager. In normal nginx you usually specify the port, so you can probably separate the forwards by port.
If it is your own domain, I’d consider to use different subdomains, then you could use dedicated ips later more easily.
