Homarr Docker using network_mode: service:vpn

I'm trying to setup Homarr via Docker using

network_mode: service:vpn

network_mode: service:vpn

to route all traffic over VPN (Gluetun). Homarr seems to be having trouble getting a node port. My same compose works when not connected via

network_mode: service:vpn

network_mode: service:vpn

. Any ideas how I can further troubleshoot or fix?
