CubicSDR can't find the SDR

I have a Raspberry PI 4, site #2682 that works when i schedule through the dashboard. However I want to used a client such as CubicSDR to run the SDR that way on occasion. I can’t connect to the SoapyServer – bind, here is some diagnostics. What am i doing wrong?

pi@raspberrypi:/tmp $ SoapySDRUtil --find

thank you.

What output do you get when executing the following:

SoapySDRUtil --find="remote=myServer" where myServer is your Soapy Remote server.

hi Pe0SAT,
i get the same message, no devices found, yet lsusb shows the device:

pi@raspberrypi:~ $ SoapySDRUtil --find=“remote=192.168.1.106”

Where is the device? I see three hubs (internal) and a wifi adapter, no SDR ?

your right, it isn’t shown in lsusb. And apparently my USB jumper cable just became defective

and I’m not looking close enough to the diagnostics

thank you Jebba

Cool. Fwiw, I found rtl_tcp to work better than SoapyRemote, but I have limited experience with both.
