FortiClient downloading updates from Fortimanager. Which port?

I've created config file to automate signatures download. I can't find in documentation which port numer is used to comunicate with FortiManager (bold one below)?

<update>             <use_custom_server>1</use_custom_server>             <server>10.0.10.123</server>             <port>8890</port>             <timeout>60</timeout>             <failoverport>443</failoverport>             <fail_over_to_fdn>0</fail_over_to_fdn>             <update_action>notify_only</update_action>             <scheduled_update>                 <enabled>1</enabled>                 <type>interval</type>                 <daily_at>03:00</daily_at>                 <update_interval_in_hours>3</update_interval_in_hours>             </scheduled_update>         </update>
