Hmm. It seems to be running perfectly. Have you tried a different browser? Also make sure this issue is not happening:

Where both your wlan and eth are configured and using same ip.

Also another thing you can check is the networking.xml. Its in the config folder. Make sure there's no configuration there that could interfere with the connection. It would be helpful in narrowing down your problem if you could also share that file as well.

Edit: oh wait I just read your message clearly. Your ip range is now 192.54.35.XXX right? What's your subnet mask? Is it 255.255.255.0? If so your subnet would be I think 192.54.35.0/24. If the subnet mask is 255.255.0.0 then the subnet would be 192.54.0.0/16. You can check your ip and subnet mask using ip a

1. Stop jellyfin
   
2. Go to the config folder
   
3. Find network.xml
   
4. Edit it
   
5. Find <LocalNetworkSubnets />
   
6. Add your subnet for example your subnet was 192.54.35.0/24 then add in <LocalNetworkSubnets>192.54.35.0/24<LocalNetworkSubnets />. If its 192.54.0.0/16 then add in that. You could try adding both just to be safe with comma separated.
   
7. Save it and bring up jellyfin and try now.
