Hi everyone. I’ve been trying Joplin the past few days on the desktop and I like it. However, when I tried to use in on iOS I couldn’t get it to sync properly. I would be grateful for any assistance.

# On iOS sync works one-way

Notes from mobile are uploaded and show in the desktop program. However, notes are never downloaded to mobile. Only the notes that were created on mobile are available.

**Version** : Joplin 10.0.47  
**OS** : iOS 13.5.1

Log:  
`There was some errors:`  
`Error: PROPFIND /: Unknown error 2 (401): 401 Unauthorized`

`Code: 401`  
`construct@[native code]`  
_15 lines in the form of:_  
`#@/private/var/containers/Bundle/Application/####/Joplin.app/main.jsbundle:###-###`  
`value@[native code]`

I triple checked my connection settings.

**Synchronisation target:** WebDAV  
**WebDAV URL:** https://###.###.com/remote.php/webdav/joplin

**Check synchronisation configuration reports:**  
“Success! Synchronisation configuration appears to be correct.”

Without success I’ve tried

- restarting the phone;
- removing and reinstalling the app;
- disabling encryption;
- to enable and disable VPN;
- disabling ‘fail-safe’;
- tried finding a solution in other topics on this forum;
- creating new app passwords for WebDAV access on the server (I have 2FA enabled).

# On the desktop sync works fine.

Joplin 1.0.216 (prod, win32)

Client ID: 41ba23c3b9034272a2da00a10355d1cb  
Sync Version: 1

Nevermind, I found the issue with status open on github.

Would be nice if there is a solution available.
