Android can't find Roon Core

Hello, here are tips that have helped me.

Make sure that the Roon app is on the list of apps not to be put in sleep mode.

How to do(Samsung):

Go to settings
Go to device maintanance
Select battery
Go to unmonitored apps (at the bottom of the page), and make sure Roon is on the list of apps that not will go in sleep mode.
If not, add Roon to the list

Sometimes my iPad throws a hissy too. To be ecumenical.

I have the latest Samsung Chromebook and my Roon app cannot find my Roon Rock even if I enter the IP address. Tried uninstall and reinstall…no luck.
Any other suggestions?

Welcome to the party. My Pixelbook was working until it got a Chrome OS update this week. Went and picked up a Surface Pro 6 Saturday night and not a single problem.

Had a long term issue with an android galaxy tab losing connection to core. Had core on iMac with ethernet connection to router and tablet was on wireless connection from same router. Eventually decided to disconnect core from ethernet (i know, should not be done !) and make set up entirely wireless (courtesy of google wifi mesh setup). Not a single issue since. Mixed protocol network definitely had some effect here…

For the umpteenth time my Android phone would not connect, so I went into help and instead of of putting the IP address of my Core I put and it found it immediately.


The trick worked! How bizarre! Thanks a million!


I am glad that it worked for others as well. Maybe Roon can pre-populate that field?

This trick even works when my Pixel 3 is connected to Google Fi VPN. Thanks a million.

I had the same problem recently (couldn’t connect at all with my Pixel 3, but have no problem with my Fire 10), and the “trick” with IP address also worked.

Great! it Works
When a Patch from Roon?

Hi @TerryD/@Milton_Krueger/@darqman/@sm31/@Andrea_Maioli,

I ran across this post and I spoke to the team about it. We would like to get some more information here as to why exactly this resolved the issue for you. Can you please let me know the following?

  • What is the model/manufacturer of all your networking gear including router, switches, range extenders, ect?

  • What type of Core are you using, Windows/OSX/Linux?

  • What version of Android do you have and what is the model/manufacturer of the device?

  • Has the new build of Roon (build 416) changed anything when trying to connect without this IP address?

  • Has this workaround not worked for anyone who has tried this?


Actually, @Noris my Pixelbook connects to the core now without having to use this trick.

The problem, for me, has been solved.

Thank you for the feedback here everyone, it is appreciated.
It looks like our last update resolved the need for this workaround which is a great data point to have.

Just had the same problem. Windows 10 core, Android tablet (Galaxy tab S4) couldn’t connect until I used as the ip. Entering the actual core IP didn’t work. My other devices, galaxy s7 phone, windows 10 machines etc were all connecting fine both wired and wirelessy.


This is the current quick fix! This works every time for me!

Hi, fairly new to Roon here – where is the 255.255… IP address to be entered?

My old phone Samsung S7 Edge connects all the time, but my new one, LG G7 One, only abour 20% of the time. Both are on Android 9.

Core is on Win 10 64 machine used solely for Roon.
