Error:0 ionic and phpmyadmin


I try to connect my database (phpmyadmin) with a typical formular to registration with ionic.
I tested this formular locally and it worked (it added in the database what I inserted in my formular)
but with ionic serve i have an error:0 and I don’t know have to resolve this error !
Can someone help me ?

Thank you in advance !

What exactly are you trying to do?

phpmyadmin is not a database but a tool to administrate MySQL databases.
What did you build the form with?
What kind of app did you build with Ionic?
