Dear all
I just did a fresh installation of Nextcloud (nextcloud-snap) on my Ubuntu 20.04 server. Port 80 and 443 are open in my router and are not blocked by my ISP.
I then proceeded to enable HTTPS with a Let’s Encrypt certificate (sudo snap nextcloud.enable-https lets-encrypt
).
I can access the server fine on the local IP from LAN (although with a cert warning). Before enabling HTTPS, I could access it fine on port 80. However, when I now try to access via HTTPS, I get connection refused:
curl https://cloud.martinlauridsen.info
curl: (7) Failed to connect to cloud.martinlauridsen.info port 443: Connection refused
This is the output of netstat:
netstat -pnltu
(Not all processes could be identified, non-owned process info
will not be shown, you would have to be root to see it all.)
