Help with opds import from Ubooquity

Maybe someone can help as I’m not the most computer savvy.
I use Fios, my router is set for my (static) IP address to see Port 2202 (library for Ubooquity)
Using Win10 with java allowed in firewall
I have Opds fees checked off in Ubooquity
When I attempt to load opds in Panels,
I put just my IP address in URL feed
In port I use 2202
In user name blank (no user name in Ubooquity)
In password I use my Ubooquity password.
I keep getting errors. Any help?

Also what do I need to do if I want to use opds to download my comics elsewhere? Same as above? Like chunky for example
