Hi,
I am a very satisfied used of Zettel Notes. However, since (I believe) one week my the connection to my Synology DiskStation acts up with permanent 403 errors. I can no longer sync notes.
My WebDAV setup goes through https, and I have changed nothing (for at least 6 months), neither on the Android side, nor on the Synology side. Port forwarding is switched off (I use the default 5006 port). On the Synology side no packages have been updated, lately. But Zettel Notes had an update, I believe. Reinstalling the app did not have any effect.
No other Android app has this behaviour: DavX and CXExplorer, to name a few, have normal access to the same WebDAV folder.
Does anyone else experience the same problem? Thanks!
