Tidal dropped out of music services

Node 2i (ethernet) , using app on Win 7& 10, Android (One Plus 8) and iPad Air (4th gen).

OK for the record, yesterday evening had an extended 4+ hours power outtage. UPS couldn't carry the home theater that long and all equipment went dark.

Fast forward to today. Most of today accessed Yamaha AVR via AirPlay  on my iPad using Apple music, no issues. Tonight pulled up Blusound controller on iPad, no Tidal listed but could used app on Win 10 laptop and Android phone  and could access Tidal fine. Reboot Node21 and Tidal reappeared on controller screen , great I thought. However a few songs in and music stopped in mid song. Could not get out of app on iPad, so sent reboot from phone. OK, back in business. Got through most of Sia album and stopped again with error message "stream timeout" , there was a an error code that I didn't write down or remember. 

Switched to Qobuz, 11 songs in and no issues (~ 30 minutes), giving it another half hour to see if it reappears. Apologies for being long winded
