Please check this image and tell me how can i resolve this and why this happened.
Hi @Shahurkh , Sometimes, the Shopify CLI will fail to create an Ngrok tunnel for you, even though it gives you an Ngrok address. But if you check your Ngrok account, there’s no active tunnels - hence the Ngrok 3200 errors you see. Try following these steps https://www.youtube.com/watch?v=NZT9DEJpmAU 
Hello, I am trying to follow this video but path not understable it’s work so please can you guide me some more steps so that my error will resolve.
Open your terminal, navigate to the root folder where you are working on your app. Example:
cd Desktop
cd MyApp
When you are in your folder, navigate to:
cd AppData/Local/shopify/sv
Then:
ls
Now the files should be listed, and one of the files should be ngrok.pid. Then enter new command:
rm ngrok.pid
Now you can go back to your app and enter
shopify app serve
New tunnel should be generated!
Happy coding!
I suppose that you’re not in the correct folder. I can’t tell you the exact solution since I don’t know how you’ve organized your ‘app’.
