【问题描述】：
我已经安装了官方包：
Information for package pgadmin4:
---------------------------------
Repository : openSUSE-Leap-15.2-1
Name : pgadmin4
Version : 4.1-lp152.2.9
Arch : x86_64
Vendor : openSUSE
...
它启动正常，打开一个浏览器选项卡。
但是，当我尝试添加服务器连接时，没有任何反应。 “服务器”下没有任何内容。
在某些时候，在卸载、重新启动和再次安装后，连接会短暂显示，但随后又消失了。
在我的主目录中，我看到两个隐藏的日志文件。 .pgAdmin4.startup.log 不包含任何有趣的内容，只是报告一切都已成功启动。另一位有以下说法：

PostgreSQL 服务器在 podman 容器中运行，但这与问题几乎没有关系。此外，我可以使用psql 连接。
有没有人遇到过类似的问题并解决了？
