1350415 - DAV_NO_DAV error with Nextcloud11 and Nginx

Status: RESOLVED WORKSFORME

(Calendar :: Provider: CalDAV, defect)

Description

[Johannes Rohr]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:52.0) Gecko/20100101 Firefox/52.0
Build ID: 20170317231433

Steps to reproduce:

Recently migrated from an Apache server with Nextcloud 9 to a Nginx on Ubuntu Yakkety, with Nextcloud 11


Actual results:

On Startup, thunderbird throws an error before even asking for the user name and password to access the caldav resource. The following errors I see in the TB error console:
jr@tommy:~$ LANG=C thunderbird
[calBackendLoader] Using libical backend at /home/jr/.thunderbird/default/ag1kqdiz.slt/extensions/{e2fda1a4-762b-4020-b5ad-a41df1933103}/components/libical-manifest

Error: Error Parsing ICS: 2152333568

In the nginx log I don't see any indication that Lightning / Thunderbird even accessed the sever



Expected results:

Well, it should continue functioning just like other DAV clients and like it did before the migration...

Found the solution here: https://help.nextcloud.com/t/thunderbird-lightening-cardbook-caldav-carddav-broken-after-upgrade-to-nextcloud-11/8511/6?u=vasyugan
Would have been solved much quicker if the error message would have hinted at SSL, which it didn't at all.
