Does HQPlayer require an internet connection?

Our Internet connection was knocked out for three days by Hurricane Helene. During that time I was able to use Roon in offline mode by itself but when I tried to use it with HQPlayer like I usually do I kept getting this error message. Does HQPlayer when used in combination with Roon need online access? Thanks.

Yes it does, at least when HQPlayer server is started.

So for example if you want to use this combination on a flight in flight mode, start HQPlayer before going to flight mode and keep it running during the flight.

HQPlayer works in standalone mode to some extent without internet connection.

Thanks, I’m not familiar with flight mode and don’t travel with my music so if it comes up again I’ll just do what I did this time our internet was out, use Roon by itself. Thanks for your help.
