Fix SABnzbd Error 10049 on Windows or Linux

If SABnzbd displays error: (10049, "Can't assign requested address") on startup, the host address in the settings may not match the current IP assigned by your network.

What Causes Error 10049

This error typically happens when SABnzbd is configured with a specific IP address that no longer applies. Many users set their system's IP manually in Config > General > Host, but this may change if the router reassigns addresses.

How to Fix It Quickly

For Windows (64-bit)

1. Open CMD.EXE using the Start menu.

2. Enter the following line:

   "C:\Program Files\SABnzbd\SABnzbd-console.exe" --server 0.0.0.0:8080

For Windows (32-bit)

Use this instead:

"C:\Program Files (x86)\SABnzbd\SABnzbd-console.exe" --server 0.0.0.0:8080

For Linux

Run this command in your terminal:

sabnzbdplus --server 0.0.0.0:8080

Manual Fix

You may also edit your sabnzbd.ini file. Locate the host setting and change it to:

0.0.0.0

This binds SABnzbd to all available network interfaces.
