Using Chunky as well for CBR/CBZ.  Most of the time for ePubs/Mobi I just import them to iBooks/Kindle apps and let it sync across all of my devices

Hey Ralph, 

Assuming you aren't using a reverse proxy or DDNS and solely for local network;

- "http://{Ubooquity_IP_Address}:{Port}/opds-comics" should work.  

- If you don't have a user name setup, you can leave those fields blank.

- If you haven't already, ensure that the OPDS option has been enabled in the Admin Console.  

Notes: normally the port is "IP:2202" for the primary server, and the Admin console is "IP:2203/admin"

Check out https://vaemendis.github.io/ubooquity-doc/pages/installation-guide.html for the install details and where you would configure the ports.
