Why doesn't xDebug work?

Question

PHP

FreeBSD 10 + nginx + PHP-FPM system, installed xDebug, config:
xdebug.profiler_enable = Off
xdebug.default_enable = On
xdebug.show_exception_trace = On
xdebug.show_local_vars = "1"
xdebug.max_nesting_level = "50"
xdebug.var_display_max_depth = "6 "
xdebug.dump_once = On
xdebug.dump_globals = On
xdebug.dump_undefined = On
xdebug.dump.REQUEST = *
xdebug.dump.SERVER = REQUEST_METHOD,REQUEST_URI,HTTP_USER_AGENT
xdebug.remote_enable = On
xdebug.remote_log="/var/log/xdebug .log"
xdebug.remote_connect_back = 1
xdebug.remote_handler=dbgp
xdebug.remote_port=9900
xdebug.var_display_max_data=10000
xdebug.var_display_max_children=10

However, nothing is hanging on port 9900 and phpStorm cannot connect to it.
There is no firewall.
Tell me what to do.
Thank you.
