WebUI Not Reachable Using Computer Name

Recommended Posts

To avoid confusion this issue is related to accessing the Web UI over a local LAN. When I posted this in troubleshooting there was confusion with people thinking I was talking about accessing it over the internet.

Devices on a local LAN have a device name/computer name. These names can be used to access services on the device. Examples might be file browsing, or a web server (e.g. http://TheServer), or a subsonic music server (e.g. http://TheServer:4040/index.view), or an Emby media server (http://TheServer:8096/web/dashboard.html), and until a recent update , uTorrent (e.g. http://TheServer:9091/gui/).

Now uTorrent no longer responds when using the computer name, giving a 400 error. Using the IP address works fine as before (e.g. http://192.168.0.51:9091/gui/). If I'm actually on the server localhost works and so does the loopback address 127.0.0.1, but not the device name, locally or over the LAN. 

This has previously been working for a few years. All other services (as listed above) continue to work with the device name just fine. 

This isn't a huge deal but I would prefer to be able to use the device name rather than IP address if possible.

Edited to add: I noticed in the change log for the last release "– Sanity check Host header on HTTP requests" among other changes to the Web UI . Wondering if it is related to this.

I'm having exactly the same problem on 3.5.3 build43916

On computer running uTorrent I can connect to webUI via "192.168.1.10:8080", "localhost:8080", and "127.0.0.1:8080", but NOT "http://computername.local:8080",

On diff. conputer, same LAN i can ONLY connect via "192.168.1.10:8080"
