Why can't a new backup start at a destination locked with a different passphrase?
Short answer: That place already holds a backup encrypted with a different passphrase, so a new one can't start there. Use Change destination, or enter the original passphrase to reconnect.
The place you picked already contains a backup encrypted with a different passphrase. Two backups can't share that spot, so a new one can't start there.
Use Change destination and pick a different folder or bucket — or pick the same one again through Change destination, which starts a fresh, separate backup alongside the old one. If the existing backup is yours, enter its original passphrase to reconnect instead.
