Webdav endpoint fails (immediately after logging in)

[rpocklin]

Describe the bug

Running the example docker compose containers located here starts up the ocis server successfully every time, however, when navigating to and logging in to `https://ocis.owncloud.test" (using 'admin:admin') sometimes (but not every time) the following request fails, which is executed by the frontend after logging in:

PROPFIND https://ocis.owncloud.test/remote.php/webdav/

Giving a result of 404 (not found).

I believe there may be a dependency-ordering or internal configuration related issue when the server starts up, given that this does not occur consistently it may be a temporal issue related to when services start and their order.

Steps

1. Start up docker compose containers (eg. using start.sh)
2. Navigate to https://ocis.owncloud.test (you may have to add a host alias of 127.0.0.1)
3. Login as 'admin:admin'
4. View the network tab (open before logging in) and check the response from the following request (PROPFIND) https://ocis.owncloud.test/remote.php/webdav/
5. Verify if you can see any folders or be able to upload files in the UI (eg. can see 'Shares' folder).

Expected behavior

The user logs in successfully without any failed API requests, repeatedly, the webdav API call should return a 207 response code with a payload.

Actual behavior

Every 3rd or 4th time the API request fails with a 404 (proxy makes request to storage-frontend which fails).
