Unable to launch the application deisigner

Hello,

I can not launch the designer. I get the following error:
Server returned HTTP response code 503 for URL

I attach a photo of the problem.

How can I solve it?

Thanks
Andrea

HTTP 503 indicates that the server is temporarily busy. We tend to see 503 when a designer tries to connect to a Gateway that is starting up. If you wait a few minutes, the designer should connect normally. If it does not connect, then you should log into the Gateway and see if there are any errors in the console, or if there is high CPU usage.
