I've been using FolderSync Pro for more than a year now to regularly
backup files from my Smartphone via SMB to a file share on my Synology
DS220j.

Last night the sync job failed, because FolderSync Pro seems not be able
to connect via SMB any longer:

java.net.SocketTimeoutException: failed to connect to
diskstation/2003:ec:d746:1800:9209:d0ff:fe0d:37cf (port 445) from
/2003:ec:d746:1800:1811:2f7d:2321:f330 (port 47910) after 5000ms

However with Cx File Explorer the very same connection works without any
issues. It also does not matter if I use IPv6 in my local WLAN or IPv4
via mobile network and Wireguard.

Does anyone else experience this problem? I already contacted the
support of FolderSync and will see, what they say about it.
