Problem getting connected on server
Soooo, what is your problem exactly? 
The problem is I am not able to signup on blynk app using custom ip and don’t know how to generate certificates in pi
Does the local server run on your Pi then?
Yes the terminal shows up that the server started up successfully
Certificates should be automatically, but it could be needed to forward port 80 to the Raspberry Pi because Lets Encrypt needs to connect to the web server over port 80 to generate the certficates (this is one time only I believe).
If you change the IP on your phone to the local server and the phone is on the same network, by all means it should work.
Are you getting any errors?
-edit
It might be prudent to post the blynk.log file here, from the logs/ directory on the pi.
Server.properties should be in the same directory as the server.jar file.
Edit and update your first post not to use template. Or it will be flagged and deleted.
I will post it soon

I updated my server just now and I am able to access admin page by not able to sign up on app it’s showing please check authentication token
Have you created a new account, via the App, while it is connected to your server? Followed by new projects… If not, you must… all Blynk servers (Cloud or LS) are separate entities from each other.
Well I figured it out I was required to configure the server.properties file
So just checking, everything working fine for you now?
Yes finally everything is working else for the emails
