Can't access offline files when Nextcloud server is down

Steps to reproduce

1. Host a self-hosted Nextcloud server on my local home network only
2. Sync the files on the server with the Nextcloud iOS app
3. Set the files on the phone as available offline
4. Turn off the computer hosting the server
5. Try to access the offline files on the phone, while leaving Wifi turned on

Expected behaviour

Files should open, since no network activity should be happening to open offline files.

Actual behaviour

Get an error that can't connect to 198.168.2.35 (the private IP address of my server on my home network).

Reasoning or why should it be changed/implemented?

I'm thinking of Nextcloud as a tool to sync my phone and computer. Once the files are synced to the phone, I should be able to access them without needing to turn off my network connection, for example if I leave my house and want to access them when I'm somewhere else.
