[BUG] failed connection

[roughnecks]

🐛 Beschreibung / Description

Hi,
The app always returns me with a failed connection when I am connected through wireguard.

2026-01-25 22:18:13.091 [ERROR] WebDavSyncService: 💥💥💥 FATAL EXCEPTION in syncNotes() 💥💥💥
2026-01-25 22:18:13.093 [ERROR] WebDavSyncService: Exception type: java.net.ConnectException
2026-01-25 22:18:13.095 [ERROR] WebDavSyncService: Exception message: Failed to connect to webdav.domain.tld/[IPv6]:443

Why the url is like that? The IPv6:port is appended to my webdav.domain.tld, doesn't look correct?
I am using this same WebDAV server from a few other clients without issues. I am self-hosting it on a VPS.

Hey @roughnecks ,

would you mind installing a debug apk and try if it works for you?

You can find the debug apk artifact here:

Would be nice, thanks in advance :)
