Thanks GreatMarko and ddubya7 for the help. Like ddubya7, my sync.conf file does not have a user/password section. I've pasted it below. I found this file at /volume1/@appstore/bittorrentsync/var/sync.conf Please let me know how I should add the user/password to sync.conf. { "storage_path" : "/usr/local/bittorrentsync/var", "pid_file" : "/usr/local/bittorrentsync/var/syncapp.pid", "display_new_version" : false, "vendor" : "Synology", "webui" : { "listen" : "0.0.0.0:8890", "allow_empty_password" : false, "directory_root" : "/", "dir_whitelist" : ["/volume1","/volume2","/volume3","/volume4","/volume5","/volume6","/volume7","/volume8","/volume9","/volume10","/volume11","/volume12" "context":"{\"folder_blacklist\": [\"\/@\", \"\/lost\\\\+found\"]}", "directory_root_policy":"belowroot" }}I'm guessing this is a bug in the setup/install on 88f628x devices.
