Unable to synchronize files

I am trying to synchronize files between two servers: server1 and server2.  I created a user and gave him permission to read, write and execute (rwx) on /var/www, and then I added the following Unison configuration file: root=//var/www/html/ root=ssh://user@server2//var/www/html/environments/simreg/ log = true ignore=Path cache ignore=Path vendor ignore=Path logs auto=true batch=true repeat=watch #confirmbigdel=true confirmbigdel=false fastcheck=true prefer=newer silent=false times=true owner=true server = true confirmmerge = true backupdir = /var/www/html/environments/backup ui = text But when I try to run Unison, it is unable to synchronize.  The debug is not useful, and I do not understand what I am doing wrong.
