Error not being connected to the interenet when connected to the internet

I’m host a next cloud instance on my laptop 6gb of ram, fedora, with the dnf package, I’m almost done setting up but there’s one weird error
This server has no working internet connection: Multiple endpoints could not be reached. This means that some of the features like mounting external storage, notifications about updates or installation of third-party apps will not work. Accessing files remotely and sending of notification emails might not work, either. Establish a connection from this server to the internet to enjoy all features.
The laptop that I’m using to host it is connected to the internet via Ethernet, and there’s another error that I don’t know hot to fix, and I don’t know if it’s related
Some files have not passed the integrity check. and when I look at the list of files there are quite a few of them and I have no clue as to how to fix it, though nothing apeers to be broken bc of it, at least as far as I can tell.
