PgAdmin fatal error. The appllication server could not be contacted

Question

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.

Answer 1

I had the same issue. Try right clicking the PgAdmin icon and clicking "Run as administrator". Worked for me.

Answer 2

worked for me if I run PgAdmin as administrator.

Right click on the .exe file and run as administrator. It will work.
