Describe the issue

Hi,

I'm having issues accessing both Roon and Roon Arc on my iPhone 16 Pro. Roon is installed on my M4 MacMini (macOS Sequoia 15.5)

I can access Arc when on my mobile network, however when at home and connected to wifi it is unable to connect and times out eventually with the message 'Roon Server Unavailable'.

When trying to access Roon on my phone on my network, I get 'Waiting for your Roon Server'. On my other devices (opening Roon on MacOS or on my Windows Laptop everything on Roon when I connect looks ok...even the status of ARC.

Steps taken:
- Recently had to re-install Roon due to general instability (end-points unable to access Roon, almost every day so just restored from backup)
- Rebooted router & home network
- Rebooted Roon (multiple times)
- Rebooted iPhone 16 Pro
- Re-installed Roon Arc
- Followed workaround of toggling Roon within System Settings > Privacy & Security > Local Network, and rebooted.

Thanks.

Hello @Alexander_Broad,

Thanks for the detailed info and the steps you’ve already taken—they’re really helpful.

Since Roon ARC works over mobile data but fails on your home Wi-Fi, and the Roon Remote app also can’t connect on your iPhone, the issue seems to be related to local network access.

Could you please double-check that both Roon and Roon ARC have permission to access your Local Network on your iPhone?

To verify:

  1. Go to Settings on your iPhone
  2. Scroll down and tap on Roon and then Roon ARC (if listed separately)
  3. Make sure Local Network is toggled ON
  4. After confirming, try relaunching the apps
Let us know if that helps—if not, we’ll dig further into other potential network issues like multicast or firewall settings.

Hi @vadim,

Checked on both apps and they were set to allow access. I toggled as instructed and restarted the apps but same behaviour.
