Strange Webdav Sync Behavior (401 -> 200)

[bitethis]

Hi,

I am running a VPS with Ubuntu 22.04 and Webdav activated via Apache2.

I synchronize some applications via Webdav, but only Enpass shows me these error messages in the log file.

 - - [02/Jun/2024:12:57:36 +0200] "GET /enpass/Enpass/vault.enpassdbsync HTTP/1.1" 401 2546 "-" "Mozilla/5.0 Enpass"
 - enpass [02/Jun/2024:12:57:36 +0200] "GET /enpass/Enpass/vault.enpassdbsync HTTP/1.1" 200 2425604 "-" "Mozilla/5.0 Enpass"
 - - [02/Jun/2024:12:57:37 +0200] "PROPFIND /enpass/Enpass/vault.enpassdbsync HTTP/1.1" 401 2546 "-" "Mozilla/5.0 Enpass"
 - enpass [02/Jun/2024:12:57:37 +0200] "PROPFIND /enpass/Enpass/vault.enpassdbsync HTTP/1.1" 207 1083 "-" "Mozilla/5.0 Enpass"

The first access always generates a 401. The synchronization itself works, but the error occurs with every first access attempt.

For comparison, a log file of another Webdav application on the same server.

- joplin [02/Jun/2024:13:10:12 +0200] "PUT /joplin/locks/1_1_f434adkkl5c2789b4b6oob65c93f9ta2b6fb369f3.json HTTP/1.1" 201 2474 "-" "Joplin/1.0"
- joplin [02/Jun/2024:13:10:12 +0200] "PROPFIND /joplin/locks/ HTTP/1.1" 207 3255 "-" "Joplin/1.0"
- joplin [02/Jun/2024:13:10:13 +0200] "PROPFIND /joplin/ HTTP/1.1" 207 5417696 "-" "Joplin/1.0"

On which operating systems does the error occur?
- Windows 10 22H2, latest Enpass version from the website
- iOS 17.5.1, latest Enpass version

What have I done to fix the error?
- Deleted Sync Settings in both applications
- Deleted all Data in Enpass Folder on the Server
- Re-enable the Sync on the devices
