How to hide /nextcloud from url nextcloud 16

No, remove the Alias completely and restart/reload the Apache. The Alias is not required in a separate config.

Since you have added the nextcloud.conf in /etc/apache2/sites-available, is this also present in /etc/apache2/sites-enabled?

If this is not the case, please use the command a2ensite nextcloud and restart your Apache.

Hello CFelix thank you for your reply
