After 11 Upgrade: Sabre Web Dav error in log

🗃️ Hosting providers
21

I can only reconfirm that - in investigating the WEB DAV error again - my hoster confirmed it would not really be an error but rather a logging output on debug as part of a natural procedure of the web dav authentification which would go away when changing log level from “0” (debug) to “1”.

I can cofirm the error message doesnt show anymore. I keep on having problems with contacts, but they may have a different cause.

however the screenshot from @jakobsystems i can not comment because i dont saw those problems. maybe a locked file?

Well, I changed log level to protocol failed logins in log. I use those log entries for fail2ban.

I concluded that “401 No ‘Authorization: Basic’ header found” messages can be ignored, at least when the client is Thunderbird + Lightning + SOGo connector. They are errors, probably in the Sabre code used by Nextcloud server (because they are seen when using a variety of WebDAV clients) but at least Thunderbird + Lightning + SOGo continues normally after the errors

This was with Nextcloud server 11.0.2 from https://repo.morph027.de/nextcloud, running on Debian 8 Jessie

The conclusion came after creating a new Thunderbird 45.8.0 profile, starting it at a command prompt (so error messages were displayed)

  • Installing add-ons …
    ** Lightning 4.7.8
    ** sogo-connector 31.0.4
    ** british_english_dictionary_updated 1.19.6 (not necessary)
    ** imap_received_date 1.0 (not necessary)
  • Calendar tab
  • New Calendar (accessed by context clicking in left pane)
  • On the Network
  • Format: CalDAV
  • Location: https://server-FQDN-redacted/nextcloud/remote.php/dav/calendars/c/personal/
  • Name: CS6
  • Email: None (only choice because no accounts set up yet)
  • Self-signed certificate steps (no glitches)
  • Synchronize Calendars (accessed by context clicking in left pane)
  • Entered user name and password

Back at the command prompt used to start Thunderbird, saw: “Warning: There has been an error reading data for calendar: CS6. However, this error is believed to be minor, so the program will attempt to continue. Error code: DAV_NOT_DAV. Description: The resource at https://server-FQDN-redacted/nextcloud/remote.php/dav/calendars/c/personal/ is either not a DAV collection or not available” (twice)

In the Netxtcloud server log saw the “401 No ‘Authorization: Basic’ header found” messages, three times once at 08:09:31 and twice at 08:12:07.

The calendar was populated, apparently normally.

hi, have the same issue with Nextcloud 12.0.0.29 and 2 Factor Auth enabled.

The Server need time to load an Month (e.g. August 2017).
Access with Thunderbird not possible:

the Log:

	Sabre\DAV\Exception\NotAuthenticated: HTTP/1.1 401 No 'Authorization: Basic' header found. Either the client didn't send one, or the server is misconfigured
