Failed to Activate Subscription - Internal Error Occured

[YankunLi]

I just subscribed to a personal ArcGIS plan and am trying to activate it. Looks like it returns me with a "Internal error occurred - 1000" for some reason. Previously, another user had asked this a few months ago, but looks like they didn't eventually come up with a solution. So here I am; please help me with this issue. Great appreciation in advance.

@YankunLiAre you using social account?

I would suggest you should reach out to Esri Customer Services for subscription related issues.

Any luck here? 

I'm attempting to activate my new license (student license) and I'm receiving the same error when I click on the link in the email to activate the license. In step 1, it instructs to click the activation link, which opens a new window in browser and displays this error.
