If SignalRGB is showing a 404 error, or the library is failing to load, it’s having trouble establishing an internet connection. There are several things that can cause this to occur. Below you will find a list of causes and solution ordered from most common to least common.
SignalRGB is blocked by Windows Firewall
To allow SignalRGB through Windows Firewall, open Control Panel and navigate to
System and Security . Then, select
Allow an App through Windows Defender Firewall .
Then, click the
Change Settings button. Scroll down to
signalrgb.exe and ensure all boxes next to it are checked. Then, click
OK at the bottom of the page.
SignalRGB is blocked by your antivirus
Some antivirus software may block SignalRGB from communicating with the internet. To fix this, create an exclusion for the path
%localappdata%\VortxEngine . Due to the wide variety of antivirus software software available, this process will differ depending on the antivirus you are using.
Your Windows username has non-standard English characters
If your Windows username contains non-standard English characters (åéñòüç), SignalRGB may not function properly. Unfortunately, there’s no easy way to migrate one user profile folder to a new one. We suggest backing up whatever data you consider important and creating a new user account name without using special characters where you can later restore your manual backup.
You have IPv4 disabled
SignalRGB communicates using the IPv4 protocol. If your network adapter has IPv4 disabled, SignalRGB will not function. To enable IPv4, open Control Panel and go to
Network and Internet →
Network and Sharing Center →
Change Adapter Settings .
Click on your network adapter and select
Properties . Then, ensure the box next to
Internet Protocol Version 4 is checked.
Properties . In the popup window that opens, select
Use the following DNS server addresses: and enter
184.108.40.206 . Then, click OK on all open dialog boxes.
Your country or ISP blocks access to certain content
If your country or ISP blocks access to certain websites or services, you may need to utilize a Virtual Private Network (VPN) to use SignalRGB.
