FortiGate: Change the HTTPS Fortigate Management Port

KB ID 0001723 Problem Like all firewalls that have ‘web management’ the default ports are 80 and 443 for insecure and secure management.

NGINX: Redirect HTTP to HTTPS

KB ID 0001617 Problem Rather by accident I discovered this was not working on the site.

Certificate Chain Incomplete

All appeared to be fine until I did an online check to make sure it was OK.  The server’s certificate chain is incomplete Solution I had this problem once before, back then I was using Apache and CentOS7, and things were a little different, (now I’m using NGINX and Ubuntu 18.04). Essentially you see this error...
