PgAdmin fatal error. The appllication server could not be contacted
提问by Dionisius1976
A couple of days before I have installed on my PC with Windows 7 Professional new version of PgAdmin (version 4). It worked fine, but today it loads slowly and then information window appears with text: "PgAdmin fatal error. The appllication server could not be contacted.". I restarted windows, but it doesn't help. Is there any solution of this problem? Thanks.

worked for me if I run PgAdmin as administrator.
如果我以管理员身份运行 PgAdmin，则对我有用。
Right click on the .exe file and run as administrator. It will work.
右键单击 .exe 文件并以管理员身份运行。它会起作用。

I had the same issue. Try right clicking the PgAdmin icon and clicking "Run as administrator". Worked for me.
我遇到过同样的问题。尝试右键单击 PgAdmin 图标并单击“以管理员身份运行”。对我来说有效。

I tried all options mentioned in link Postgresql can't connect application server through PGAdmin4.
我尝试了链接Postgresql can't connect application server through PGAdmin4 中提到的所有选项。
But none of the options worked, then launching C:\Program Files (x86)\pgAdmin 4\v2\runtime\pgAdmin4.exefrom command prompt worked fine.
但是没有一个选项有效，然后C:\Program Files (x86)\pgAdmin 4\v2\runtime\pgAdmin4.exe从命令提示符启动工作正常。

I had to reinstall it, as Steve suggested in comments. Then it started working again.
正如史蒂夫在评论中建议的那样，我不得不重新安装它。然后它又开始工作了。
It's probably best to start with Ray Jowa's solution -- try right clicking the PgAdmin icon and clicking "Run as administrator".
最好从 Ray Jowa 的解决方案开始——尝试右键单击 PgAdmin 图标并单击“以管理员身份运行”。

1) in C:\Users(your username)\AppData\Roaming delete folder pgAdmin (AppData - is hidden folder) 2) run pgadmin with administrator.
1) 在 C:\Users(您的用户名)\AppData\Roaming 中删除文件夹 pgAdmin (AppData - 是隐藏文件夹) 2) 以管理员身份运行 pgadmin。

This was odd, my PATH variable which had the python interpreter in it was somehow a factor, I do not completely understand though, right after I removed it everything worked, I will look further into it but so far I think that if you have python interpreter it might be the one causing the issue.
这很奇怪，我的 PATH 变量中包含 python 解释器在某种程度上是一个因素，但我并不完全理解，在我删除它之后一切正常，我会进一步研究它，但到目前为止我认为如果你有 python解释器它可能是导致问题的原因。
