If you're having trouble connecting to your Vercel deployment, you might be asked by our support engineers to run these debug commands.
Run the below mentioned command, depending on your operating system, from a terminal of your choice. This script will conduct various checks, and depending on different factors, it may take up to 15 minutes to finish. When complete, it will create a vercel-debug.txt file in the current working directory, which you then can attach to your open support case with Vercel Support.
