I recently started a new position that uses Siemens technology (so forgive my lack of knowledge). I am just trying to simulate an HMI but anytime I do, it will compile okay but when it launches the window, it gives me an error. I've tried looking at the PG/PC interface but there are so many options that I'm not sure which is correct. Then, a coworker told me to look at the Configuration Tool. When I try to generate a certificate, I get an error during Web Configuration. I can only assume all of this is connected. Any help would be much appreciated!

Hello! Unfortunately I am still having the same issue.

Thanks for responding Costanza!

The project is indeed green and started in Runtime Manager. 

I am using a MTP700 Unified Basic HMI and I am at V20 Update 4 for Unified. I've also created a second project with an MTP1000 with the same result. 

Yes, that is the error I'm getting in my browser. I just requested access for the fix!
