The source folder is /dcim/ and the destination folder is /social/dress/red
the configuration folder is /social/ but got this error? can not use the subfoder for the destination folder?
According to your screenshot, the directory /home/social/dress is owned by root while the other directories around it are owned by an unidentified user with UID 911 (although not impossible, usernames on a Unix/Linux system normally begin with a letter).
If Syncthing is running as user/UID 911, then the permissions on that destination directory needs to be changed from root to 911.
