    This is a important milestone for me who is doing scientific literature management and reading every day. PDF annotation and notes export function are so usefull.
    In addition, I also installed and used the app, but I found a problem that the app can't connect to synchronization WebDAV server。

    What platform is this? Can you provide a Debug ID for a verification attempt that fails?
  • Yong_Joon
    @dstillman I installed and used iOS app. To sync attachment file in my Libarary using WebDAV, I click Settings->Account, and I selected WebDav in FILE SYNCING option. when I click "verify server", there is a error tips "Could not connect to WebDAV server". I'm sure my WebDAV server is working properly because I can synchronize files every day。

    We'd need a Debug ID to say more.

    The same problem happened to me.
    Here is a Debug ID: D1644195188. Log started when clicking "Verify Server".

    The same configuration is applied to Zotero 6.0 on Windows and Zotero on IOS. It works on Windows but not on IOS.

    I'm having the same problem. The webdav sync works on my PC, but on the iPad app I got a cannot connect to server message. The debug ID is: D1290784408

    Thank you

    IP address like “192.168.123.1” is working. The domain name like “google.com” is not working. This issue is not happen in windows and macos.

    @xxx_account: It sounds like you're trying to connect via HTTP rather than HTTPS. iOS only allows HTTP connections to local addresses.
  • xxx_account
    @dstillman I use the “192.168.123.1” just for an example. Actually my address is “220.xxx.xxx.xxx” and I connect to my webdav via http. I also try to connect my webdav service via https with the domain name but it’s still not working. Maybe the DNS services cannot resolve my domain name.

    @dstillman Apparently the IP address is working and the domain name address is not working in my iPad. I tried to change the DNS services in WI-FI preferences but it still not working.

    I am experiencing a similar problem: verification of the WebDAV-Server using Zotero for iOS does not terminate (Debug-ID: D2039560692). It does work with Zotero on Windows.
  • dstillman Zotero Team
    (+0015822): HTTP OPTIONS https://webdav.[…]/zotero/ failed with -1
    @eichler: Is there anything unusual about your network connection? Using a proxy? Network firewall? Have you tried restarting your device?
  • dstillman Zotero Team
    @xxx_account: You shouldn't be able to connect to any non-local addresses via HTTP on iOS. If you're having trouble with an HTTPS connection, we'd need a Debug ID.

    @dstillman: Sorry, mistake on my side: it has been a typo in the user name. But it have been reported in the UI (did only show the processing icon).

    @luchao91: There's no Verify Server attempt shown there. Can you try again?

    @iami667: That's a server incompatibility that should be fixed for the next version.

    @ekcheng2: You're just entering the wrong URL.
