Problem to activate AutoCAD 2018 Establish an internet connection to continue

[Jay_one]

Hello Community! I ask for your great support to guide me and can solve the error that comes to me when trying to activate AutoCAD 2018. The message that I receive at the moment of logging in to activate my product of deleclipcion is the following:

"Establish an internet connection to continue"

I have applied all documented solutions and recommendations from Autodesk pages but with no results. also was formatted to the hard disk completely, the antivirus was deactivated etc etc etc and this message continues to appear. the rarest thing is that if I manage to logon on A30 and the desktop application without problems. the problem happens when I try to validate the license, then I put my ID I get that. already tested all the ports, we connect in a network that has no restrictions and neither, outside the domain does not work either. please someone who can help us !!!!! please !!

Hello Jay_one

It looks like you're seeing the "Desktop Subscription Licensing" error. This error sometimes occurs due to an Autodesk licensing hotfix, lack of proper connection like network flow is blocked by Proxy Server or an Autodesk Servers Issue. The following article(s) should help you resolve the problem:

Hi @Jay_one,

I checked your account and it's not associated to an AutoCAD subscription. On the other hand, it's associated to a Maintenance Plan for several products, including AutoCAD. As this is a Perpetual License, to activate the software you won't need to enter your credentials, but you'll need the Serial Number and Product Key. Please contact your Contract Manager to obtain these license details.

Regards,

Hello, Thank you very much for your response, 

my ID is not associated, but the problem arises with licenses that we buy in my work is the case of a user who 
can not activate his license by subscription, I have already formatted the hard disk and it happens the same, 
in another equipment if it was possible.

Hello, I installed a previous version of AutoCAD and it works without problems, thanks for your answer 
I will continue to investigate the issue of activation 2018 since I have applied all the solutions
 and I still get the message that there is no internet. does not validate the subscription.

Thank you.
