Nextcloud version : `27.3.2` Operating system and version: `Debian bookworm (RPIOS bookworm` Apache or nginx version: `2.4.56` PHP version: `8.1.25` The issue you are facing: I installed ncp and nextcloud through the Raspberry Pi image and have in running well (a bit slow 😉 ) on a RPI4 4GB. I access it through a local custom domain (with a self-generated certificate) and can access nextcloud on [https://mydomain](https://mydomain) and ncp on [https://mydomain:4443](https://mydomain:4443). That’s great and was pretty easy to install! I also installed the nextcloudpi-App in nextcloud. My problem is that the app-icon does not point to the ncp-install which is already running. Instead of the ncp install (which is accessible through [https://mydomain:4443](https://mydomain:4443)), I get an empty page with: `{"message":"CORS requires basic auth"}`. The adress-bar contains `https://mydomain/apps/nextcloudpi/` Is there a configuration file, in which I can enter the required link, to which this icon should point - or is there another way to get the “ncp-app-button” open ncp (if necessary a fresh install?). I like the concept of accessing both nc and ncp from the same link. Thanks for suggestions. Is this the first time you’ve seen this error?: I think it’s always been there. It’s not an error, I think, just a missing configuration. Steps to replicate it: Press the nextcloudpi button/icon in an install that was started from an RPI-image. ---

Yes that it is because you don’t have the 4443 port open on your router I think, I am in the same situation. You can open this port but it better less port open outside your internal net ---

Afaik ncp admin page :4443 is only accessible from within LAN for security reasons. So one should always use localIP:4443 Best to use ssh and use ncp-config to access from outside. ---

I am tryin to access ncp from inside my LAN, and ports can’t be closed, as I can access ncp by running `https://mydomain:4443` within the lan - provided the host I am accessing _from_ knows which ip to resolve `mydomain` to, which - for the time being - I achieve with a manual entry in the hosts file. However, now that I come to think of it: what kind of link or “connection” does the nextcloudpi app use to access ncp? Does it internally use a http-link, or does it expect ncp to reside in a certain filesystem-position relative to the nextcloud site? I’d expect it to use `localhost:4443`, which should be domain-name independent. But likely this works in an entirrly different way anyhow? ---

After much searching, the “CORS REQUIRES BASIC AUTH” error when you click the nextcloudpi button appears to be a bug. The workaround is to not use that button. Hopefully they fix it someday or at least remove the button. > > > uBlockOrigin blocks https://ownyourbits.com/category/nextcloudpi/ so I couldn't …look there. > > https://github.com/nextcloud/nextcloudpi/wiki/FAQ makes no mention of CORS > > the documentation page at https://apps.nextcloud.com/apps/nextcloudpi is a 404, but the link to report leads to here, and I could find no mention of the app called nextcloudpi, this appears to be about the distro nextcloudpi (which I am enjoying). So I don't even know what that app would do if it worked, however it appears by default on the dashboard, and when clicked it displays a text page with only a CORS error, the user is then locked out and sometimes the server is left in a locked state. > > considering the /settings/apps/installed/nextcloudpi shows this app as version 0.0.1 I'm hoping I can just remove it. I am going through and replying to all these CORS threads with a message pointing to this bug report so people will have an answer. ---
