Cannot onboard and delete Gateway

Cannot onboard and delete Gateway

I onboarded a new gateway on TPE as usual but this time it got stuck at Initialization and cannot be online. I check the gateway at local and it already received internet, i had experience and did the onboarding successfully many times.

Then i tried to delete the Gateway and re-add again but didn't work and got this error:
