Unable to add WebDAV mount from Hetzner Storage Box

[Ypnose]

Problem scope

• I'm sure that this is a DAVx⁵ problem.

App version

• I'm using the latest available DAVx⁵ version.

Android version and device/firmware type

Android 16 (GrapheneOS)

Steps to reproduce

I tried to add a WebDAV mount from Hetzner Storage Box. It says there is no available mount found at this URL. The URL can be accessed with browsers (Firefox, Chromium) or with rclone (webdav config). When accessed with browsers or curl, it displays Apache server.
I'm not sure it is a fully WebDAV compliant server, maybe DAVx⁵ is unhappy about that.

Would be awesome to support it, though.

Regards

Hi, we do not have access to any Hetzner account to test this. Have you followed the steps here?

In the mean time, can you share some logs with us? Follow this guide. Otherwise we cannot help much...

If you don't feel comfortable sharing them through here, we have a secure channel available in this form: https://www.davx5.com/support

It's not in the system unfortunately, somthing must have gone wrong. Although everything seems to work, since I got another ticket in the morning. Please can you try again?

[Ypnose]

Of course, did it right now !

[devvv4ever]

Still no ticket... Very weird. Please send it directly to play@bitfire.at.

Our ticket system didn't work properly but it should work again now. Please give it another try. Sorry for the inconvenience!

Thanks for your message. I did it one minute ago.

Hi, thanks for the login details, and sorry for the issues with the ticket system, they have now been resolved.

I'm trying to diagnose this, and it looks like the server is not properly configured to support WebDAV. I've tried to mount it using the file explorer, and it says that it's not a WebDAV share. And manually performing checks responded with: Allow: GET,POST,OPTIONS,HEAD,TRACE. PROPFIND, MKCOL, DELETE... Should be shown there.

Have you followed the steps on Hetzner's guide?

Before you follow this how-to guide, open the overview of your Storage Box in Hetzner Console to check if WebDAV support is enabled. If not, select the action "Change settings" and enable WebDAV support. After you activate WebDAV, it can take a few minutes before you can access your Storage Box via WebDAV.

And when the WebDAV option is disabled, you also cannot access it with a browser.

[ArnyminerZ]

Strange... Can you report it to Hetzner? Being able to access it through the browser doesn't mean that it's compliant with WebDAV. Maybe they have something wrong... I'm not sure how is it working with rsync though.

Thanks for your help. On DAVx⁵, you confirm me everything is good ? In theory, it should work, right ?

Yes, it should. However, if you need any more help from our side, please don't hesitate to contact again. And if integration works fine, we'd happily include Hetzner in our tested-with page.

Your support is very well appreciated. I will contact Hetzner about that, in the following days.

Hello there, I finally received an answer from the support. On Hetzner, WebDAV cannot be accessed with a read-only account, it must have read-write permissions.

Read only access disables WebDAV actions. You would therefore need to give the sub-account write permissions.

I successfully enabled the mount in DAVx⁵ after this change.

Now, having an option in DAVx⁵ to set the mount as read-only (as it is done in Agendas) would be perfect. :)
