I updated my CyberPanel instance a few days ago using the Install/Upgrade command since the panel was not up to date. Once the upgrade was successful, I happened to notice the ImmunifyAV component in the Security section of CyberPanel admin interface and clicked on it to check it out and possibly install it.
Since it looked like a convincing plugin, I clicked on install now and I am not sure what exactly happened, nor do I have the log saved but it seemed like the installation had failed. I refreshed the page to make sure that was the case and was faced with an access now button which when I clicked displayed not found error
Just figured out how to install ImmunifyAV on CyberPanel if the installation through the dashboard failed but you are seeing the ‘Access Now’ button and get redirected to a page which says, ‘Not Found’, ‘The requested resource was not found on this server’
