Ruckus ZF7055 can not join ZD3000

[eko_budhi_harso]

Hello..

I have Ruckus 7055 with standalone firmware 104.0.0.0.1347
And my ZD300 firmware version is10.0.1.0 build 151.

I already reset 7055 to factory default, ssh to 7055 and give command set director ip x.x.x.x and then reboot, but looks like 7055 can no reach ZD3000, I can ping ZD3000 from inside 7055.

Any help would be appreciated.
