There’s no need to use the playground; deploying on a single machine has fewer issues.

Thanks, I just tried deploying without using the playground, and it was successful. However, opening the dashboard gives a 404 error, but Grafana can be opened.
Check with tiup display, then look into the PD logs to see which URL is returning a 404.
Awkward, I didn’t enter the full address. I missed “/dashboard” at the end. Now I can access it.
It’s normal when you first start, you’ll get used to it. Remember to mark the best answer 
Glad to hear it’s resolved. Feel free to visit often.
I heard you’re interested in the Dashboard, you can also check out the column.
