Server is NUC i7
Roon server won’t start by itself
But if I run the roon app the server starts with it and all is fine
Only then can my iPhone see the running server
When I exit roon app on the NUC the server also exits
and the iPhone can’t find the server
In task manager I can see when sever starts and stops
It also seems that you must’ve changed something yourself, because what you say can’t have worked as you say.
If you’ve got only Roon (with GUI) installed, then music will of course stop when you terminate the application - that’s a fact.
If you want Roon server without GUI, you need to download and install Roon server.
Then, if you want a GUI on the same PC, that you can start and stop at your discretion without the currently paying queue stopping, you need regular Roon installed in parallel as well.
Then something is wrong. Running both at the same time works and what I’ve done for 8 years. You install server and then install roon connecting to the server.
The issue may have arisen with the latest build of RoonServer. There have been reports that when RoonServer updates to this build, it stops working. This looks as though it happened to you, so you downloaded Roon (not RoonServer) and then Roon appeared to work. However, now the Roon Core being used was not the Core in RoonServer, but the new Core in Roon.
What you need to do is download RoonServer from the Roon Labs download page and reinstall it and run it. This should get it working again.
Then go to Settings > General and press the Disconnect button on your current Roon Core (which will be the Core in Roon). Then you should see both Cores show up for you to choose and connect to the Core in your RoonServer.
All your playlists should still be available and your Qobuz albums get synced to all Cores that are being used, so you should be good to go.
Maybe look for Roon server app in your start menu first, and if available start that, then do the disconnect full Roon core, reconnect Roon server core, and you should be okay.
Then, in the task bar, locate the Roon server logo, right click and activate start up on system start.
From there on, things should be as you were used to …
