If you see the IP address as 127.0.0.1, that is not a usable address from anywhere but the computer the calibre content server is running on. See
Loopback Address for more information.
If you check the Connect/Share icon in the toolbar or Sharing over the net in preferences, you'll see something like:
Code:
Content server listening at: 10.0.0.59, port 9231, HTTP
or
Code:
Stop Content server [10.0.0.59, port 9231, HTTP]
Create your URL for those examples as:
Code:
http://10.0.0.59:9231
If you still have an issue from a mobile device, you could try:
Code:
http://10.0.0.59:9231/mobile
I'd also suggest check the
calibre Content server page.
