Error when opening pgAdmin 4 on mac

Question

I have installed version 4-1.5, but when opening it, it always shows this error \"The application server could not be contacted.\"

Answer 1

On my system Safari is the problem as it was default browser.

To fix, make Chrome your default browser and try relaunching pgadmin4

OR

Manually fix by $ cat ~/.pgAdmin4.5704814747986328352.addr http://127.0.0.1:62631/?key=0ec25e6a-dfe2-483e-9814-b315ea87c3cf

Paste what you get in Chrome
