A “Network Error” means the extension couldn’t connect to the internet while trying to perform an action.
This usually happens if your connection drops, is unstable, or something is blocking it.
Make sure you’re connected to the internet
Open a website in your browser to confirm everything is working
Switch networks if possible (for example, Wi-Fi to mobile hotspot)
If you’re using a VPN, proxy, or firewall, try disabling it briefly to see if it’s interfering.
Restart the extension and try again
Reload or restart your browser
Clear local data: Options → modcore Snapshot → Data Management
Make sure you’re using the latest version of modcore Extension Manager
If the error keeps showing up even with a stable connection, send a report with a short description of when it happens. That helps identify whether something is being blocked or failing in the background.
