I’ve got jellyfin and nginx proxy manager running in two separate containers. What do I need to specify in known proxies? The ip is changing frequently which means I can’t use it.

I try setting the ip in the compose file but something is wrong. nginx proxy manager:

22     networks:
23	 npm:
24         ipv_address: 172.20.0.2
25
26 networks:
27   npm:
28     driver: bridge
29     ipam:
30	 config:
31         - subnet: 172.20.0.0/24
32           gateway: 172.20.0.1
33

and

jellyfin:

32     networks:
33	 npm:
34         ipv_address: 172.20.0.3
35
36 networks:
37   npm:
38     driver: bridge
39     ipam:
40	 config:
41         - subnet: 172.20.0.0/24
42           gateway: 172.20.0.1

jellyfin log: [16:08:01] [INF] [16] Emby.Server.Implementations.HttpServer.WebSocketManager: WS 172.20.3.11 request

can someone point me into the right direction?
