pgadmin4 : postgresql application server could not be contacted.

Question

I have installed PostgreSQL 9.6.2 on my Windows 8.1. But the pgadmin4 is not able to contact the local server. I have tried several solutions suggested here in stackoverflow

Answer 1

I was able to solve the problem by changing the pgAdmin web interface port.

I believe this problem occurred on my computer because I have several other services consuming webs ports like qBittorrent, IDEJetbrains, etc.

Right-clicking on the pgAdmin logo near the clock is possible to configure it.
