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: “”. But I’m trying to acess the WebUI with this: “” but it says that the connection has failed.
I’m using this: where under the section WebUI is described what I’m trying to do. Any ideas what I’m doing wrong?
