Plugin registration tool connectivity issue

Hi All,

I am facing issue while connecting to plugin registration tool, my crm is 365 trail(10 days trail left)

The issue is once i provide the username and passowrd to O365,then i am able to see the organisation details like (login to xyz) and then it will go to login page.

Registratool:

2016 online(8.2.1),

also i tried with 2015 SDK

Both the above versions i facing the same.

If i try with the non trail crm application(365 online), i am able to connect(no issues).

For trouble shoot, i create a fresh trail instance but the issue is same,is there any issue with trail version connectivity for O365?
