解决方式:

1. C:\Users\Administrator\AppData\Roaming\pgAdmin之内的删除所有文件和文件夹

The application server could not be contacted

2.C:\Program Files\PostgreSQL\10\pgAdmin 4\web 找到config_distro.py文件

The application server could not be contacted

添加:

MINIFY_HTML=False
DATA_DIR = "C:/Data/pgAdmin" # set non-ascii path here

则为:
