I know that topic has been around for a while and some people have their problems with the following issue, including myself:
Omnipresence is kind of sensible when it comes to the WebDAV servers it shall talk to. I know that there is no single WebDAV standard, but nevertheless it’s a bit annoying.
I’m running a synology NAS with DSM 5.0, WebDAV enabled on http and https. The compatibility check of omnipresence fails with the following error message:
We could not connect to your selected cloud location.
Could not access the WebDAV location https://xxx.hostname.xxx:5006/webshare/Omnipresence/OmniDAV-Conformance-Tests/fortestReplacedCollectionUpdatesModificationDate:%20/parent/tmp/doc/.
Please make sure that the destination folder exists.
I googled a bit and learned that I’m not alone. But I found no feasible solution to solve this issue. I don’t want
to install a debian chroot and install an apache WebDAV on the synology NAS (ok, maybe I want, but I dont’t know howto do it).
There is an Owncloud Package for my Synology NAS. So I tried to install Owncloud in a virtual linux machine and tested if I can connect Omnipresence to the Owncloud WebDAV server. Guess what? Doesn’t work. Not compatible.
I googled a bit and again I learned that I’m not alone: https://github.com/owncloud/core/issues/8033
The owncloud developer finally said that probably there’s a bug in Omnipresence. Ok, that’s easy fingerpointing, but hey, I’ve connected already so many WebDAV clients to my WebDAV server and never had an issue.
I would really really love to connect Omnipresence to the Synology WebDAV Server. By the way: Omnifocus 1 and 2 (both on Mac and iOS) have no problems to sync with the Synology WebDAV Server.
If the omni group does not want to fix this, then maybe somebody out there has an idea what I might do to sync Omnipresence to my NAS.
Currently, this issue keeps me from investing some money to buy Omnioutliner for Mac and iOS.
Thanks in advance and
