Running Roon on QNAP 471 flawless until now... HELP

I have run into a problem where now I am unable to locate roon server remotley. Continues to say “waiting for remote core”. I have reboot the qnap, with no success. I am considering reinstalling roon but wanted to reach to first if there is any suggestions. The other reason I would consider to reinstall is because roon does not accept my tidal login in! Help please…

Did anything change in your setup? Like a QTS update or RoonServer update, new network gear?
