Lost ability to connect to my core

See photo. I am using the CAPSZUMA not the sonictransport. Trying on my Lenovo tablet. Core is connecting to a PC on my network, however. I am 10 feet from the wifi router so it should not be a signal issue with the tablet. What further info can I provide to help decipher this here? Thanks. JCR

I will answer my own question. I uninstalled and reinstalled Roon remote on the tablet and it found my core on the reinstall. I should have tried that first before posting! JCR
