IPs in LAN networks -> no Jellyfin server found

[phoenix22]

Since updating to Jellyfin 10.9.1 I have the following problem:
 
As soon as one or more IPs are listed under

  Settings -> Dashboard -> Networking -> LAN networks

my Jellyfin server can no longer be found. Only when I delete the network.xml from the config folder and restart the docker container will my Jellyfin server be found again. If I enter IPs again into LAN networks, my Jellyfin server can again not be found anymore.

These IPs under LAN networks have been working until the update to 10.9.1.
 
Does anyone has an idea what the problem is here?
 
Example
My Jellyfin server can be found at 192.168.178.9:8096
In the field LAN networks, there are 192.168.178.15,192.168.178.16,217.XXX.XXX.XX1,217.XXX.XXX.XX2 listed.

Do you have remote connections disabled? Generally you provide CIDRs for that field instead of specific IPs. Is your client at one of those IPs?

Yes, remote connections are disabled

Is your client at one of those IPs?

Yes. I use several clients (Android, Android TV, Jellyfin Media Player Windows, Web). And each IP has one client.

You are setting up them wrong. It is meant for network segments not IPs.

Ok thanks.

Perhaps the description of that field should be changed:
"LAN networks ...
Comma separated list of IP addresses or IP/netmask entries for networks that will be considered on local network when enforcing bandwidth restrictions. If set, all other IP addresses will be considered to be on the external network and will be subject to the external bandwidth "
