Hi! What’s not quite right with Roon?

· Can’t reach my Server, remotes or ARC

Can’t connect to my Server, remotes or ARC

· Other ARC issues

Tell us what's going on

· Roon ARC war nicht bereit sicher auf deinen ROON Server zuzugreifen

Tell us about your home network

· Fritz!Box 7490, 1GB Switch

Hello @f.lomp, welcome to the Roon Community

That message (“Roon ARC war nicht bereit, sicher auf deinen Roon Server zuzugreifen”) usually points to a connectivity or port-access issue between ARC and your Roon Server.

As a first step, please go through the following three articles — they cover all supported ARC connection methods, including setups with and without manual port forwarding:

1. ARC overview
   https://help.roonlabs.com/portal/en/kb/articles/arc
2. ARC with port forwarding
   https://help.roonlabs.com/portal/en/kb/articles/arc-port-forwarding
3. ARC without port forwarding using Tailscale (recommended if port forwarding is not possible)
   https://help.roonlabs.com/portal/en/kb/articles/arc-and-tailscale-connect-to-roonserver-without-port-forwarding

Please follow the steps carefully and test ARC again afterward.

If ARC still can’t connect after this:

• Open Roon → Settings →Roon ARC
• Then send us a diagnostic report from Settings and let us know roughly when you tested

We’ll take a closer look based on the diagnostics.

Hi, everything is fine now. I have forgotten to open the port in the Speedbox which is before the FRITZ!Box.
