CardDAV and Synology can't set up

DAVx⁵

    I’m looking for some support please.

    I’ve got a Synology NAS running the current version of DSM (DSM 6.2.2-24922 Update 4). I’ve installed CardDAV server, and pointed DAVx5 on my android device to the server according to the exact instructions of https://www.davx5.com/tested-with/synology

    The response is weird:

    • If I connect using http I get no response at all.
    • If I connect using https I get a response, but only Calendar features show up, no CardDAV address book is found
    • I can connect to ip:port for either http or https from the android browser, and there is a server there.

    The log appears to report an authentication failure, but the password is being pre filled by a password manager on my phone. The same password manager I use to log in through my PC browser. And it sort of half works on https, so?

    An example log:

    --- BEGIN DEBUG INFO ---

    Hello,

    @ronaldo said in CardDAV and Synology can't set up:

    If I connect using http I get no response at all.

    2019-12-07 19:12:39 2118 [HttpClient] <-- 301 Moved Permanently http://10.0.1.3:8008/.well-known/carddav (12ms)
    2019-12-07 19:12:39 2118 [HttpClient] Location: https://localhost:8443/

    Your DiskStation redirects from http://10.0.1.3:8008/.well-known/carddavto https://localhost:8443/, so the detection fails (because localhost is the Android device itself and not the DiskStation).

    So, this is a configuration problem on your DiskStation.

    If I connect using https I get a response, but only Calendar features show up, no CardDAV address book is found

    Can you post the logs for that? Are you sure that you have used the CardDAV URL? Are you sure that the name and password combination is correct? Are you using 2 FA?

    I can connect to ip:port for either http or https from the android browser, and there is a server there.

    You can try to access the CalDAV/CardDAV base URL with your Android browser, and it should ask for username/password. When you then enter it and get something other than 401 Unauthorized, all preconditions are met so that a CalDAV/CardDAV server could possibly run at this URL.

    Thanks for the response. Do you know what might be causing the redirect to localhost? The CardDAV server on the NAS is installed as a package, and there are very few configuration options… nothing that would cause a redirect. The calendar package is also installed and a connection to that on http:// works fine and even shows the cardDAV features your setup guide advises not to use.

    I can’t post a log of the successful connection on https:// which has no CardDAV features, as no log is generated if the connection appears to set up correctly. When I create and set up that account… I get these setup optionssettings CardDAV url.jpg

    As you can see down the bottom, CardDAV shows up, but there are no options. I am absolutely 100% certain that I’m using the correct CardDAV url and the correct username and password. There is no 2FA.

    Connecting to the base cardDAV url in the browser gives the following:httpURLinAndroidBrowser.jpg

    An attempt to connect to the /addressbooks/users/NAME URL gives a username/password prompt but results in 401 Unauthorized even when using the correct username and password.

    Is there some secret about setting up the CardDAV package on the synology NAS? It shouldn’t be this hard, but I can find no user permission options in DSM relating to CardDAV or calendar.

    I would recommend to ask this question in the Synology support forum, The DAVx5 forum is definitely the wrong place if the intial authentication fails.

    @j-ed Thanks for the suggestion, but DAVx5 is selling this app as tested with Synology Nas

    https://www.davx5.com/tested-with

    My installation is exactly as stated in the set up instructions, so DAVx5 should be able to diagnose the problem.

    You can imagine the Synology staff probably won’t be interested in supporting a third party app that doesn’t even run on their hardware.

    Hi ronaldo,

    Well, your interpretation of ‘tested-with’ probabely does not take the biscuit. It’s not about selling any Synology app such as CardDAV server with DAVx5, but more of indicating basic compatibility. And in fact, Synology CardDAV server works in general with DAVx5 which I can confirm from my own experience.

    Second, DAVx5 cannot be made responsible for some strange behaviour (e.g. redirection) outside the scope of DAVx5 and the expectation ‘should be able to diagnose the problem’ is of course desireable however not very realistic.

    Third, using a Synology forum similar to this one is not about bothering Synology staff, more about asking other Synology users.

    Back to the issue, redirection may occur for several reasons. So there are several potential places to cross-check. Since you logs show CardDAV standard ports for http and https, it would be worth to have a look at the CardDAV settings for redirection from http to https. Furthermore, you might also want to check the DSM reverse proxy for potential redirection of the port in question.

    However, the easy way out might be - at least temporarily for testing purposes - to deactivate http to https redirection in CardDAV server and setup any device with https.

    Good luck!
