Why can’t I reconnect to my removed AXIS Device Manager Extend Site?
If you have selected to remove a site that has been claimed and added to your organisation previously, it is not possible to undelete it.
The only option is to uninstall and reinstall the site controller on the local pc. Uninstall via the start > Settings > Apps menu. Reinstall using the installation package available on axis.com and select Site controller only.
