Installation
Other addons are not working any more
Disable HTTP Inspection
In your menu under "Networking" disable "Inspect fetch requests" and "Inspect post requests". Often addons using a DRM will not load if http requests are intercepted for security reasons.
Check Serverlogs
Restart your server and see if you spot any error messages of the addon not working.
Check Health Tab
In your menu under "Health" check if there are Nova Defender errors.
Type nova into your server console and check if the command works. If not, check if you installed Nova Defender like described on GitHub.
Check if you are listed as protected player
Type nova list list into console and check if your SteamID appears. If not, add it via nova add "YOUR_STEAMID" "YOUR_USERGROUP" "COMMENT" (don't forget quotes) and check again with nova list.
Type nova help or nova if you need help with this command.
Try opening via console
If the chat command !nova is not recognized, you can try entering nova into your ingame console.
Usage
Too many detections or notifications
By default you will get asked for each detection. This is to prevent innocent players from getting banned.
Select Disable in future. You can reenable it every time in the menu by changing action nothing back to ask, ban, kick or notify.
If you think a detection is wrong, please open a ticket to further improve the product.
