Joplin sync failure on IPv6 only networks.

[AesaraB]

Environment

Joplin version: Flatpak 2.8.8
Platform: Linux
OS specifics: Fedora 36

Steps to reproduce

With Dropbox on an IPv6 network:

1. Set up Dropbox sync (may need to do so on IPv4 enabled network)
2. Attempt to synchronise database
3. Joplin tries to connect to https://content.dropboxapi.com using it's A (IPv4) DNS record instead of the AAAA (IPv6) record.

Last error: FetchError: request to https://content.dropboxapi.com/2/files/download failed, reason: connect EHOSTUNREACH 162.125.83.14:443

I've never developed with Electron/Node.js before, but this is probably an upstream bug, see: signalapp/Signal-Desktop/issues/4121

Comment

I'm having the same problem, I'm not able to sync my Joplin with Dropbox when I'm on IPV6, but when I'm on IPV4, the sync works. I then had to disable IPV6 for synchronization in Joplin to work.
