Port configuration

HTTP and HTTPS port configuration

By default, the snap will listen on port 80. If you enable HTTPS, it will listen on both 80 and 443, and HTTP traffic will be redirected to HTTPS. But perhaps you're putting the snap behind a proxy of some kind, in which case you probably want to change those ports.

If you'd like to change the HTTP port (say, to port 81), run:

sudo snap set nextcloud ports.http=81

To change the HTTPS port (say, to port 444), run:

sudo snap set nextcloud ports.https=444

Note that, assuming HTTPS is enabled, this will cause HTTP traffic to be redirected to port 444. You can specify both of these simultaneously as well:

sudo snap set nextcloud ports.http=81 ports.https=444

Note: Let's Encrypt will expect that Nextcloud is exposed on ports 80 and 443. If you change ports and don't put Nextcloud behind a proxy such that ports 80 and 443 are sent to Nextcloud for that domain name, Let's Encrypt will be unable to verify ownership of your domain and will not grant certificates.

Also note: Nextcloud's automatic hostname detection can fail when behind a proxy; you might notice it redirecting incorrectly. If this happens, override the automatic detection (including the port if necessary), e.g.:

sudo nextcloud.occ config:system:set overwritehost --value="example.com:81"
