Owncloud Client Disconnecting

## Describe the bug
Owncloud clients on many machines keeps disconnecting approx. every week, requiring user to re-connect in the client (it's of course worse, because this fails silently, and users don't realize that their files aren't being synced).

## Steps to reproduce
1. Install & Setup OCIS
2. Install & Setup Client
3. Log in on client
4. Wait a week

## Expected behavior
Client to stay logged in

## Actual behavior
Client disconnects after a week, requiring re-authentication

## Setup
Owncloud Client 5.2.1 on Windows
Owncloud Infinite Scale Server 4.0.2 installed on "bare metal" on Xubuntu 22.04.3 LTS
- with certbot

Happy to provide any logs, though it is still unclear to me how to get these logs.
