thanks people, but i found the error:
I entered to the Integration Server Administrator port: 9999 and in the Security section click in Ports, then in the port admin table, select Edit in the column IP Access for 5555 row, now click the 3rd link: "Change IP Access Allow by Default ", and the job is done.
Result:
Port IP Access SettingsAccess TypeAllow by Default
*Note: The Deny List should be empty.
