Magento PWA: issue in starting development server

I solved my problem, hope if it may help anyone else.

The issue was that I was not having the root access and due to which it was not working.

** If any one else faces this issue please delete content of

"/home/narendra/.config/devcert" folder completely and try again with root user.

(In my case option to enter password was also not coming but on deleting this folders content at least I was on initial stage. )

Hope if it may help someone
