I think there's a specific community for PTC Creo Direct Modeling Express 6.0, but I can't find it. Ryan Kelley‌, can you move this to the right community where he can get the help he needs?

There is currently a general issue with the PTC License Server.

Looks like the problem is back? I get the same messages as indicated above.

*bump* Is the activation service broken again? I get proxy configuration error messages on two different systems on two different networks.

For the last few weeks, I'm having this problem every time I use Creo Direct Elements. Internet otherwise works fine. Any suggestions?

Hi Ben, having the same issue. Express worked well since the initial download on 7/30/23 but now does not start. Instead a pop up dialogue prompting me for email and password to Activate comes up. After entering my e-address and password. and selecting 'Activate' I get a second dialogue saying: Connection failed. For Modeling Express to automatically activate it requires access to the internet. Please check if a proxy has to be specified and enter your company's proxy server details so that activation can proceed. I'm merely an individual with a laptop, there is no proxy server. My internet connection is fine and I have a basic PTC account with a valid password. Frustrating to be sure.
