Cant access :4443

Hi all,

I’m having an issue trying to access the WebUI on my NextcloudPi. I can access the normal Interface using the local IP of the RPI: “https://192.168.2.114”. But I’m trying to acess the WebUI with this: “https://192.168.2.114:4443” but it says that the connection has failed.
I’m using this: https://docs.nextcloudpi.com/en/how-to-configure-nextcloudpi/ where under the section WebUI is described what I’m trying to do. Any ideas what I’m doing wrong?
