Lets-encrypt Nextcloud Snap Problem

Hi,

Can anybody help? I have installed NC Hub SNAP on Ubuntu. Internal network - Works fine

  • Created a domain to point at it
  • Added port forwarding for 80 and 443
  • Added a reservation in my router
  • Can access everything internally without a problem
  • Next I ran sudo nextcloud.enable-https lets-encrypt (This seemed to go through its motions)
  • Then rebooted ubuntu
    Now when I access externally with FireFox, Chrome or Edge, I get “Site is not secure”

No errors when installing lets-encrypt. Am I doing or missing something fundamental

Any advice would be very very welcome

This has been solved. I watched a few guides and it turns out I hadn’t additionally opened 80 and 443 in Linux
