WebDAV Server: Authentication failed - only for DT and DTTG?!?

tja · June 20, 2024, 9:22pm

I have a very strange problem:

Since today, all my DTTG instances and my DT instance complain about “Authentication failed” for the WebDAV sync location.

I use the same WebDAV account for files and for my Strongbox password safe - the user and password work fine for them!

But suddenly DT and DTTG don’t work anymore.

I disabled the sync location in DT and tried to create a second configuration with the same credentials, and it did not work - it failed directly with “Authentication failed”.

I then mounted the WebDAV volume in macOS and everything looks fine!
Any idea what could be the cause?!?

Posting “ls” output next …

I exchanged my user name by “<“USER”>”

tja · June 20, 2024, 10:42pm

I updated my Mac to 14.5, but the problem did not vanished with the reboot.

Of course, the fact that also all DTTG instances are affected, it needs to have a different cause anyways.

Just telling what I tried.

Chridi · June 21, 2024, 6:29am

Hi!
Same Problem here. Since the day before yesterday.
A Friend of mine is also facing this problem.
Desktop and iOS.

We are both using ionos hidrive, as @tja does.

I am afraid ionos changed something.

At first i thought, they damaged the existing (encrypted) SyncStore, but when i try to add a new unencrypted SyncStore, i fail with “Authentication failed”.

greetings

typhoo · June 21, 2024, 6:49am

Also the same issue here. Both Ionos and Strato Hidrive (different brands but same company) are affected. Ionos’ status page displays all services as operational. So it seems we need to reach out to their support instead.

Chridi · June 21, 2024, 7:15am

what surprises me is that access via Firefox, for example, works without any problems

chrillek · June 21, 2024, 7:44am

How do you access a WebDAV location with Firefox and how do you know that it works?
Last time I checked, browsers didn’t speak WebDAV.

tja · June 21, 2024, 8:03am

I think, there are plugins for Firefox.

But I see the same with MountainDuck and Strongbox.

They use exactly the same credentials, beside the DT encryption password, the database name and path to the database.
And those work.

tja · June 21, 2024, 8:04am

I will call IONOS support.

tja · June 21, 2024, 8:18am

I am calling them right now.
Support seems clueless.

rmschne · June 21, 2024, 8:19am

did the WebDAV port change?

tja · June 21, 2024, 8:24am

None of the Apps asks for a port.
It’s just a https URL.

chrillek · June 21, 2024, 8:33am

Did you try anything else with the webDAV folder except listing the content? I’d suggest to open Wireshark and have it log the traffic on port 443 to your Ionos/HiDrive location. What error messages do you see there?

I find it highly improbable that DT/DTTG suddenly (i.e. without any updates to them) change how they work with WebDAV. Nor did I notice any webDAV issues with my NAS sync location.

tja · June 21, 2024, 8:50am

No, of course DT is not the problem.

Something small changed at IONOS, this seems to be clear.

But the problem can of course also be related to something small that DT does different to the other Apps.

I can try to analyse in the evening.

smarty · June 21, 2024, 9:10am

Same problem here! I use HiDrive from Strato. I called the support yesterday and they told me that they are aware of the problems with the webdav access and expect to solve these problems during the evening. Unfortunately, this is still not working.

Chridi · June 21, 2024, 9:13am

hmmmm,
i only tried to access via https://webdav.hidrive.ionos.com/users/…
could be, that firefox doesn’t use WebDAV then…

i am not sure…

tja · June 21, 2024, 9:20am

I informed IONOS about the situation at Strato, so they can ask them

tja · June 21, 2024, 11:41am

To all Strato and IONOS customers:

Could you please contact the support too?

This may help to get this sorted.

tja · June 21, 2024, 1:22pm

IONOS support is kind of creepy
