### Steps to reproduce

I'm not sure about how to exactly reproduce the issue but I'm in holiday and my server at home isn't reachable, which is normal. What isn't normal is that the nextcloud doesn't show any data. It used to do so, and I've updated the client recently. Also, the data is still physically present locally, just not visible in the client.
