WebDAV Database Failing With 401, 403, 424, 404 (DAVKit Error) or Similar

When you use WebDAV, the error codes returned are actually the standard HTTP status codes. This means we can look them up via web search, or simply at https://httpstatuses/com.

For example, if your server is returning 403 we can look here:

https://httpstatuses.com/403

This indicates that your server is saying the request is "Unauthorized" or "Forbidden". From here, this is likely to be a configuration issue on the server. The best thing to do is to look at the server logs and find out why it is failing.
