help me? pls?

I have a problem with the ruijie AP 720 every day I have to turn off at least 2 - 4 time for the device to restart so it can be used again, the problem is POE often can't receive data to continue to the AP and causes the device not to get IP, I've tried all I have applied the existing configuration methods starting from macc, fit, fat, and all the topology models, but it's still like that, when the network error "no internet" POE flashes in green and blue, can you help me?

Hi, sir
May I know what PoE device you re using to power AP?

Dear sir
Sorry for reply lately.
Please type 'show ver' in the CLI of this AP to check if it's the latest version. If not, you may upgrade it to the latest firmware, the following is the link for latest version

And please type 'debug pdpoe-test 0' , ' 'debug pdpoe-test 1
'，‘debug pdpoe-test 2
’ this 3 commands to check its poe type when this issue happen.
best regards
