Question:
How can we update Nebula firewall's SSL certificate so when user's reach the 2-Factor Authentication page from the Remote VPN it does not show the site (192.168.2.1) is not secure?

Answer:
Currently, Nebula does not support importing third-party SSL certificates. You can avoid the unsafe warning by changing the 2FA link from HTTPS to HTTP in your VPN profile.
