How to Connect to a WebDAV Server on iPhone

Add a WebDAV server in Fileso using its host, port and path, then check uploads and common connection errors.

A WebDAV connection lets you work with files stored on a server from your iPhone or iPad. In Fileso, you add that server as a remote source and browse its folders alongside your other file locations. You need the WebDAV endpoint supplied by your storage service or administrator.

Use the WebDAV endpoint, not the website

A storage service may offer both a website and a WebDAV address. They are not interchangeable. The endpoint can include a path after the hostname, and some services require an app password rather than the password used for interactive sign-in.

For example, an endpoint such as https://storage.example.com/dav contains three separate settings: HTTPS, the host storage.example.com, and the path /dav. This is an illustrative address; use the actual details from your provider.

Enter the connection in Fileso

  1. Open Add Connection, name the source, and select WebDAV.
  2. Choose the required Scheme Type, HTTP or HTTPS.
  3. Enter the hostname in Address and fill in the account credentials.
  4. Under advanced settings, check Port and enter the endpoint’s Path.
  5. Save the source and open a folder to verify that listing works.
  6. Upload a small test file to a folder where the account has write access, then download it again.

Use HTTPS when your server provides it. Changing the scheme alone cannot add HTTPS support to a server that has not been configured for it.

Fix common connection failures

A login rejection can mean incorrect credentials, an expired app password, or an endpoint that belongs to another account. A missing folder or unexpected HTML page often means the path points to a website rather than the WebDAV service.

If browsing works but uploading fails, check folder permissions, server storage limits, and any upload limits imposed by a reverse proxy. Retest with a small file before repeating a large transfer.

Keep a local copy for a trip

A saved connection still needs a reachable server. Download important documents before you leave your network and open those local files once while disconnected. That check confirms the content is on your phone rather than merely visible in a remote listing.
