Illuminate \ Database \ QueryException：SQLSTATE [HY000] [2002] php_network_getaddresses：getaddrinfo failed：提供nodename或servname，或者不知道

Question

I'm currently working on my Laravel project and I keep the error below while running PHP artisan migrate. I'm using Xampp on my mac.

Illuminate\Database\QueryException :

SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo failed: nodename nor servname provided, or not known

Mysql database is running on this url: http://localhost:8080/phpmyadmin/

I attach my .env file.

Can anyone can help to explain this error and how to fix the problem?
