Can't Verify WebDAV server on iOS

kyleweng327
I'm using WebDAV sync with my Synology NAS.

In my iPhone,
1. When I click most of literatures they will shows "Error The attached file could not be found" , and the bottom shows "Finished sync (105 issues).
2. When I go to "Settings/Account/Verify Server", it shows "Could not connect to WebDAV server"
It happened might around a few months ago.
3. Debug ID D891975304

In my Windows PC, Zotero sync works very well with my Synology NAS.

Could you please help me resolve this problem?


Thanks!

    We'd need to see a Debug ID for a Verify Server attempt.

    That's the same Debug ID. Again, it needs to be a Debug ID for actually performing Verify Server.

    I performed it again, and the Debug ID is: D1491027262. Thank you very much!

    The certificate for this server is invalid. You might be connecting to a server that is pretending to be “10.[…]” which could put your confidential information at risk.
    It's an invalid certificate. Note that the iOS app doesn't support self-signed certificates.

    Thanks for your quick reply.

    I've been using the 10.[…] link to connect my Synology via WebDAV, and the sync has worked well for years.
    (Thank you also for pointing out the potential security risks. I learned the method online and wasn’t aware it might be unsafe.)

    However, a few months ago, it stopped working on my iPhone and iPad, though it still works on my Windows PC.

    Do you have any suggestions for reconnecting my Synology?

    Thank you very much.
